Book Report: Practical Psychomancy and Crystal Gazing by William Walker Atkinson (c) 1908

Background Information: The Publisher, The Yogi Publication Society is a press started by William Walker Atkinson at the turn of the 20th. century to promote his writings on "New Thought," which was the New Age movement of the time. Atkinson himself was quite a character. He was a prolific writer, with over 150 books to his credit, often under any of several pen names. He rose to prominence at the beginning of the 20th century, but seems to have become forgotten in the following decades, though he and the Yogi Publication books are experiencing a new renaissance at the beginning of the 21 century.
Many of the books were written by Atkinson, but they also published other prominent metaphysical works by other authors. The company has changed hands a number of times, so many that the original history was lost to the current owners, but the books are still in print, and still inspiring spiritual seekers. 
While he used other pen names for his books on Yoga and other esoterical, he usually reserved his own name as author of books on psychic sciences. 

This is another little booklet published by the Yogi Publication Society, slightly less than 6 inches tall but containing over 90 pages of information for developing your psychic skills. The first chapter describes the scientific theory behind psychic phenomena and the human aura ans well as telling you about the five psychic senses, which are the same as our physical senses, but operate on the psychic plane. He goes on to offer basic ways to develop you abilities though concentration and visualization and includes us of the crystal ball, or an inexpensive substitute, which, as with most authors on the subject, he considers primarily a tool to help focus and strengthen your mental concentration. 

Despite it's small size, the book covers all the basic psychic skills including clairvoyance, clairaudience, crystal gazing, astral projection, past and future seeing and even dream psychomancy. 

Of interesting note is the description of The Psychic Tube. I don't know whether this is a creation of Atkinson, but it was also included in several prominent courses in meditation and mental development. In a nutshell, once you've developed your psychic abilities and you want to send a message to someone far away, or perhaps you just want to take a look atd what's going on there, you imagine a tube of psychic power stretching from your mind to your target and send or receive through it.  Does it work? I'd love to hear your experiences! 

This book is out of copyright and reprinted by a number of presses. You can still find the Yogi Pub version currently on sale, as well as vintage copies for your collection.

Book Report: How to Converse with our Spirit Friends by Alexander (Alexr) Vernon

 Alexander (Alexr) Verner is listed as the "founder and Principal of the British Psychological Institute." I have not been able to find much information about Verner or the British Psychological Institute (there is a British Psychological Society, but apparently unrelated). Verner appears to have been an author of a number of small, straightforward booklets on metaphysical and New Thought topics including, "How to Converse with Spirit Friends," "Table tapping and Spirit Writing," "Medical Hypnotism and Suggestion." He appears to have been British, writing at the turn of the 20th century, around the height of the New Thought Spiritual movement. His booklets were sold in America through William Walker Atkinson's Yogi Publication Society. I can't help but wonder if Verner is actually one of Atkinson's many Pen-names. 

Since the release of the movie The Exorcist in the 1970s, popular media has regaled us with cautionary tales of a world of malevolent spirits all around us, and care must be taken lest they turn our lives into an endless Halloween double feature. But a century ago, people were very anxious to mane friends "on the other side" and learn about the disincarnate world. This book hales form that time, when seances to talk to the dear departed were a common experience. Perhaps the fact that TV and Radio didn't yet exist had something to do with it. 

In yet another of Verner's practical little guides to otherworldly topics, the author outlines everything you need to know to get started hearing voices. Interestingly, he starts of with his theory of the way the spirit world world, based on the latest scientific findings of his time. He proposes the physical world is made up of atoms and molecules, but the driving force that gives them shape and motion is the spirit, and since science believes that beings are continually changing their atoms, it's only the spirit that maintains the form,. He further surmises that, in the case of celestial and disincarnate beings like angels and ghosts, they have physical bodies in some other realm, but when they are called to travel to Earth to deliver messages, the spirit can separate from the physical and travel to Earth, where they can mobilize molecules here to incarnate long enough to say what they have to say, then their physicality dissolves and their spirits travel back to their home somewhere else in the universe. He even surmises that the universe is full of Heavens all occupied by different sorts of incarnated spirits. Neat. 

He outlines a basic method for solo exploration using a small table as a communication tool. He advises sitting in a small room with your palms on the table and focusing on the table until you begin to feel the signs of a spirit present. Then ask it to knock on the table and begin to set up rules for communication. You know these from old movies: rap once for yes and twice for know, etc.). If you seer a light or "star" floating around the room, keep your eyes on it and it may develop into a face. It may deliver a message to you. 

He Describes "Elementals" which seem to be simple basic spirits that appear as insects, objects or small animals that indicate a good or bad situation. These appear to be omens of or premonitions, and not strictly spirit communication. He describes seeing animals on people shoulders that predict death or illness, seeing wedding rings on girls' hands who are not yet married, and even stripes on a policeman's uniform before he won a promotion. 

He includes a very weird experiment which reads as if taken from some medieval grimoire, which involves mashing up a plant, sealing it in a jar to ferment in a dungheap for six months, distilling it through a complicated alchemical process and then heating the resultant fluid over a candle, and a vision of the plant will gradually appear, which is the essence of the plant, looking exactly like it did before you tortured it. 

He discusses seeing apparitions and what they might mean, and also goes into working with spirit guides, who are generally eager to help you, but if you do get a bad one, just banish him firmly. Also be sure to lead a good and proper lifestyle because bad guides like bad people and hate working with good ones. He touches on guides as taking control of the medium, but doesn't provide near enough information on that tantalizing fact, aside from the medium making noises and gestures motivated by the guide's control. 

towards the end of the booklet, he touches on the argument of whether the spirit messages are actual spirits or just information picked up telepathically, a reasonable question. Because the nature of a lot of spirit communication is in the form of premonitions that no one could possibly have known, he reasons out the possibility of telepathy. 

The book is replete with examples of the author's own experiences in seeing signs and getting spirit messages. Unfortunately, many of the deal with predicting death and injury --though not all-- so it makes some cautionary reading. I'm not sure I want to practice a skill so full of visions of doom!

Anyway, it's a lot of fun information in a small 34 page booklet! 

 It's worth noting that while  his other books lack copyright dates or any indication of the period in which he's working, except what can be divined by the current trends and fashions in the author's writing, This one dies have several dates specific to phenomena he observes. He mentions doing a reading in September1917, Seeing howling dog signs in 1916 (a harbinger of death!) and discusses perceiving a lot of deaths in the "South African War" which would be the Second Boer War 1899-1902. Of special note, he mentions the howling dog phenomenon before his father died in 1881, when he was 12, which would mean he was born in 1869. Interesting stuff if anyone wants do do a little detective work.

Book Report: Medical Hypnotism and Suggestion by Alexander (Alexr) Verner

 Alexander (Alexr) Verner is listed as the "founder and Principal of the British Psychological Institute." I have not been able to find much information about Verner or the British Psychological Institute (there is a British Psychological Society, but apparently unrelated). Verner appears to have been an author of a number of small, straightforward booklets on metaphysical and New Thought topics including, "How to Converse with Spirit Friends," "Table tapping and Spirit Writing," "Medical Hypnotism and Suggestion." He appears to have been British, writing at the turn of the 20th century, around the height of the New Thought Spiritual movement. His booklets were sold in America through William Walker Atkinson's Yogi Publication Society. I can't help but wonder if Verner is actually one of Atkinson's many Pen-names. 

This one was of particular interest to me as a hypnotist. While no copyright date is given, the work is clearly the product of the late 19th century. despite the title, it is actually an outline of Mesmerism, which is different. In the brief outline of the history of hypnosis, he indicates the three major schools of the 19th century: Liebault, Charcot and Mesmer. (Modern hypnosis comes principally from Liebsault and his Nancy school. In the 20th. century
Elman and Erickson would become the defining voices for hypnotism). He also refers to Phrenological term, a debunked science of brain anatomy based on the shape of the skull and brain underneath. 

The author claims to have studied with a number of 19th century experts in the field, including Dr. Herbert Parkyn of Chicago, a Dr. Dtayton of the Eclectic Medical College, and several other experts in New York and on the Ward's Island Insane Asylum (!) 

The book gives a concise outline of the procedure of Mesmerism, which includes making "magnetic passes" with the hands up and down the length of the subject's body. Passing downward puts people into trance and upward to dispel it. He recommends half-hour sessions several times a week until trance is achieved. (Other authors have indicated that Mesmerism is a slow process). Mesmerism is more akin to faith healing or Reiki healing, believing that the Mesmerist projects a "magnetic fluid" from his hands towards the subject to effect cures. 

He touches on the basics of induction, some applications for stage hypnosis, methods for diagnosing and treating medical conditions (He does caution to be sure client is also examined by a doctor). One of the odder things is directions for inducing a week-long trance, which was apparently something like a modern medically-induced-coma, Presumably for more rapid recovery form some trauma (The author acuatally doesn't indicate why you'd want to put someone in a trance for a week, but he does suggest the client consume certain substances that will cause constipation, so the need for a bathroom won't wake the subject up). 

There's a chapter on "autosuggestion" which is to say, using repeated affirmations in order to change one's bad habits and poor health. These are pretty basic.

For a little booklet of 37 pages it covers a lot of interesting elements of a now mostly-forgotten practice, but it's probably not enough for an aspiring practitioner to work with.

Book Report: Practical Psychometry by Alexander (Alexr) Verner F.A.I.P.

Alexander (Alexr) Verner is listed as the "founder and Principal of the British Psychological Institute." I have not been able to find much information about Verner or the British Psychological Institute (there is a British Psychological Society, but apparently unrelated). Verner appears to have been an author of a number of small, straightforward booklets on metaphysical and New Thought topics including, "How to Converse with Spirit Friends," "Table tapping and Spirit Writing," "Medical Hypnotism and Suggestion." He appears to have been British, writing at the turn of the 20th century, around the height of the New Thought Spiritual movement. His booklets were sold in America through William Walker Atkinson's Yogi Publication Society. I can't help but wonder if Verner is actually one of Atkinson's many Pen-names. 

 Psychometry is the skill of psychically "reading" and object to perceive information about the object's history or it's owner. A psychometrist might handle a person's hat or gloves or watch chain (considering the period in which this booklet was written) and sensing information about that person's health, emotion and possibly even future. According the the author, medical psychometrists were very much in demand by the public.The book is very straightforward in it's approach-- he recommends the student to develop his sense of touch by handling many different items and noting the impressions. He elaborates on this very practical approach, and is very encouraging. 

There is also a "table of Impressions" suggesting the meaning of the sensations you might have when giving a reading. For example, a "Bouyant" read might indicate Hopefulness, while a sense of a sharp pain in the ankles can indicate Rheumatism, and so forth.

One interesting note is that he credits Professor J. Rhodes Buchanan for discovering psychometry and first demonstrating it in New York in 1842. (It's my impression that it's one of those classic psychic skills that goes back to antiquity). 

In one chapter he suggests different specialties a psychometrist may have particular aptitude for in phrenological terms (Phrenology was the now-debunked science analyzing a person's temperament and abilities based on the shape of the head and brain). 

He closes with half a dozen examples of readings taken from his own practice. They are interesting ut somewhat depressing, since they mostly describe diagnosing illnesses and dangers. 

It's a fun, inexpensive little tutorial, apparently by an actual practitioner of the art, and currently in print.

Book Report: Light on the Path by Mabel Collins (c)1885/1970

Mabel Collins was a noted member of the British Theosophical Society, occultist, vegetarian, suffragette and anti-vivisectionist. She wrote a number of books on Theosophical topics but eventually left the theosophical society due to differences with some of the members, notably H.P. Blavatsky. As an interesting side note, she briefly lived with occult author Robers Donston Stephenson, suspected of being Jack the Ripper. 

Light on the Path is considered one of the classics of Theosophy. It's a brief booklet consisting of two parts, each  of which is divided into a series of aphorisms or rules to help students further their spiritual development. 

The aims of this practice include self discipline, mental development, intuition, inspiration and motivation. The booklet also includes a chapter on the nature of karma and how it relates to the student.

Theosophy was a sort of a New Age movement of the 19th century. It combines mysticism with Hindu and Buddhism. There's en emphasis on meditation and inner development for seeking spiritual wisdom.

This little book is a series of short ruled that, if followed and exercised should lead one to a higher wisdom. They are somewhat vague and general as one would expect, but it's been a classic for over a century. I imagine it's a practical guide for seekers of all sorts of disciplines.

Book Report: Six Lessons in Crystal Gazing by Ra Mayne (R.A. Nelson) (c)1928

Robert Nelson, AKA Dr. Korda Ra Mayne was a pioneer in the performance art of Mentalism which includes mind-reading and fortune telling shows as well as doing magic shows. He was a radio personality and performed weekly for seven years. A prolific writer, he was one of the first to publish books on the "secrets" of mentalism and magic performance. 
Through his company, Nelson Enterprises, he sold equipment and courses for magicians, mentalist, astrologers and psychics. 
Much of this biographical information comes from around the internet and this tribute page: https://www.mevproshop.com/secret-domain-of-dr-ramayne/nelson-biography.html

This is another of the mail order booklets that Nelson produced and sold through the mail (see: Are You Mediumistic?). 

Though it's a small stapled booklet on Newsprint paper, it's seems to be one of the more thorough books on Crystal ball reading, and probably a good one to start with. Newer versions are paperback bound.

Some years ago, I got curious about the trance states involved in crystal ball reading and ended up reading a lot of books on the subject, even though I never actually wrote the paper. I suppose that may have been the origin of my collection of books on Mental phenomena!

One of the main points repeated several times throughout the book is that the Crystal ball is merely a tool for focusing the attention and the mind, and a glass of water or a spot of ink can be used just as well (but he did sell high quality balls at reasonable prices!). He also makes clear that the images you see will appear in your mind's eye not actually in the ball. Some other authors suggest you might see visions in the ball or in your head, but the minds eye seems to make more sense to me (not that I've had much practice). 

He lists a number of exercises that he recommends practicing. Interestingly, the first exercise is to ask questions in your mind, like "what did mother goose' house look like?" and see what images come into your head. This is clever and probably trains the mind for imagery better than just staring into it to see what comes up, which is the most common exercise in other books,. there are several other exercises. 

Since he is clear the the crystal ball is merely a tool to focus the mind, he also suggests using it to recall memories, work on self improvement, fight stress, and even find inspiration. He talks about how, while writing his books, he would stare into the ball while organizing his thoughts, and he felt it helped him focus and get inspiration. 

Of course he also suggests using it for telepathy and even gives some interesting experiments you can try with friends. 

The oddest part of the book is the final section which describes a "true Hindu method" for influencing people to feel great affection towards you. It sounds like something out of an early 19th century manual, and despite being give as "Hindu," (a popular appellation for all things exotic in the previous century), it stresses "proper Christian" behavior and values! 

Overall a worthy addition to any scryer's bookshelf.

Book Report: Are You Mediumistic? by Korda Ra Mayne (R.A. Nelson) (c) 1932

 Robert Nelson, AKA Dr. Korda Ra Mayne was a pioneer in the performance art of Mentalism which includes mind-reading and fortune telling shows as well as doing magic shows. He was a radio personality and performed weekly for seven years. A prolific writer, he was one of the first to publish books on the "secrets" of mentalism and magic performance. 
Through his company, Nelson Enterprises, he sold equipment and courses for magicians, mentalist, astrologers and psychics. 

Much of this biographical information comes from around the internet and this tribute page: https://www.mevproshop.com/secret-domain-of-dr-ramayne/nelson-biography.html

 This is a straightforward, no frills, outline for the budding medium or psychic. In a scant 20 pages it has basic information to get anyone started in seances and mediumship, Automatic writing, crystal gazing, telepathy and psychic healing, and more, but it's clear enough that it probably provides everything a person needs ot get started. 

The author's premise is that while everyone has the potential to develop psychic skills it takes a lot of work ond you never know which specialty you'll succeed in without practice and experimentation. And mediumship, the ability to communicate with spirits, is a gift that few possess, but is worth working on. 

This booklet appears to have been printed in many different formats with different cover art since the 1930, and one source says that Nelson Enterprises, the original publisher, also produced versions of the book without the author's name, that could be customized for other resellers. 

My copy, the one shown in the photo above, Lists the publisher (but not copyright!) as Stanray Industries 1971. The facing title page lists the author as "Anonymous," and the back of that page, in smaller letters at the bottom, says Copyright 1932 R.A. Nelson. 

The last few pages list several other publications to appeal to the aspiring psychic, including The Book of Forbidden Knowledge, Six Lessons in Crystal Gazing, and an offer for an astrological reading.

Book Report: Entangled Minds --Extrasensory Experiences in a Quantum Reality by Dean Radin (c) 2006

Dean Radin, MS, PhD, is Chief Scientist at the Institute of Noetic Science (IONS) and Associated Distinguished Professor of Integral and Transpersonal Psychology at the California Institute of Integral Studies (CIIS). His original career track as a concert violinist shifted into science after earning a BSEE degree in electrical engineering, magna cum laude and with honors in physics, from the University of Massachusetts, Amherst, and then an MS in electrical engineering and a PhD in psychology from the University of Illinois, Urbana-Champaign. For a decade, he worked on advanced R&D at AT&T Bell Laboratories and GTE Laboratories. For over three decades, he has been engaged in research on the frontiers of consciousness. Before joining the research staff at IONS in 2001, he held appointments at Princeton University, SRI International, and other academic and industrial facilities.

He is author or co-author of hundreds of scientific, technical, and popular articles, five dozen book chapters, and five best-selling books.
(the above was taken from his bio at the Institute for Noetic Sciences https://noetic.org/profile/dean-radin/)

Most of the books I collect and write about are old 70s "mind science" books about mental or psychic phenomena, and they generally come in two varieties, either they're just a series of anecdotes, or they're sort of how-to guides. If there's any discussion of how these things might work, it's usually the traditional metaphysical talk taken from traditions like Hinduism, Buddhism, Taoism, etc. So when I heard about this book, I had to check it out.

The book explores the uncanny similarities between psychic phenomena like clairvoyance, telekinesis and precognition with observed phenomena of Quantum physics.

The book is very logically presented and entertainingly written, leading us through categories of "psi" that have been researched, methods of testing and statistical analysis, (and how to spot errors like accidental or deliberate omissions in data). Naturally he also describes the way the psychological tests are structured, both in order to get the purest data and also to avoid any kind of bias. 

The discussion of quantum physics is clear and understandable. One of the early scientists involved in Quantum research defined much of what he observed as "spooky action at a distance," and this is where the corollaries to Psi phenomena come in. Some of the more mind-blowing concepts in quantum physics include "nonlocality" whereby things can interact with each other even when separated by distance or time and the strange quality whereby atomic particles can be particles or waves depending on the way they are observed, and each state has very different qualities. 

Even the title of the book, "Entangled Minds" refers to "quantum entanglement, which is the strange way that, once particles have interacted, they continue to interact forever, no matter how far they're separated.   

The book is thought provoking and a fun read whether you're a true believer or a hardened skeptic or anything in between. and you'll also come away with a better understanding of Quantum Physics and statistical analysis.  

----

I do feel the need to mention one of the other books I've reported on, Science and the Supernatural, by John Taylor. Taylor was a top scientist back in the 70s and 80s, and took the bold step of attempting to find a scientific basis for psychic phenomena. At the time he was writing, mainstream science was even more hostile to Psi research, and quantum physics was still mostly exotic theory. Unfortunately, he reasoned that telepathy and psi phenomena were a manifestation of radio frequencies, but never was able to get his theory to work. Nevertheless, his mere willingness to participate in the study ruined his career. How things have changed!

Book Report-- When she was Bad by Patricia Pearson (c)1997

When she was Bad, Violent Women and the Myth of Innocence by Patricia Pearson (c)1997

Hot on the heels of the notorious Heard V. Depp trial (June 2022), I heard about this book, and it certainly piqued my interest. I'm not usually interested in the true crime genre, but the bizarre soundbites that kept showing up on social media drew me in, and so did the extreme responses of the fans. 'Nuff Said.  

This book is a deep dive, not exclusively into crimes committed by women, but moreso Western Society's perspective on women and crime, both social, legal and scientific. And it may not be what you think it is. Specifically the theme is "the nature of female aggression."

Exploring a number of specific crimes committed by women in detail and examining the public, legal and scientific data about them, the author found that our culturally influenced attitudes about women as the "weaker sex" have created an environment which serves badly both for the victims of women's aggression and for the the women themselves.

In order to clearly highlight the influence of our culture, which is primarily a Western/Christian influence, the author compares cultures less influenced by implicit patriarchal beliefs, where women may be as accepted as aggressive and physical as men, something that, to our culture seems very alien. For example, our western attitude is that women are the better sex, the purer one, but also the one that doesn't think for itself, and never acts, but only reacts. (at the time the book was written, the term "patriarchy" was not in usage as it is now).   

The author manages to walk that razor's edge social attitudes on one side and hard data on the other in order to shine a light on the difficult-to-look-at facts that women are fully human, fully equal to men in all ways, including aggression and violence. At the same time, her writing stays witty, clear and highly readable.

The author manages to span a number of important places and perspectives to give us a thorough picture. She opens the book by looking at other cultures where womens' aggression are more believed and accepted. On an island off Venezuela, for example, it is accepted that women may be as strong or stronger and more violent than the men, and it is a point of pride, something they call Parar El Macho to balance male aggression. In aboriginal societies in Australia and Africa, aggression and violence is about equally initiated by males and females, and women have even been known to lead genocides. 

She also describes her initial difficulty in finding psychological research here in America on women and aggression, simply because most researchers didn't see the point, since their patriarchal attitude precluded the idea of female aggression.  

The book goes on to explore the world of female serial killers, women who murder their kids, women in prison and more (a recent edition, released in 2021, includes a new chapter on medical caregivers and violent crime). Each chapter presents its facts and premises clearly and colorfully (sometimes too colorfully), but with an engaging narrative style, and even a touch of humor. 

Perhaps nowhere is the troubling dichotomy made more obvious than the chapter on women who kill their own children. In previous chapters we find women literally getting away with multiple murders because the authorities sees women as both unable to initiate violence, and too good and pure to really hurt anyone. But one of the many things revealed in this chapter is that many of the mothers who killed their babies actually sought help before they committed murder, but were disregarded as merely suffering normal post-partum depression, and that their natural maternal instincts would soon kick in and make motherhood wonderful for them.

If you were ever fell afoul of the mean girls in school when you were little, if you ever had a bad divorce, if you were ever victimized unjustly by a woman but were told you must be at fault because "women don't do that," you may find this book quite cathartic.

Book Report: Master Guide to Psychism by Harriet Boswell (c)1969

 Harriet Boswell  was an enthusiastic experimenter in the area of Psychic abilities. She founded the Aquarian Research Center in Florida, a nonprofit center which offered classes and workshops in ESP research. It was dissolved in 1984. This book appears to have been popular enough to have gone through several printings, at least two in hardcover by Parker Publishing, and several in paperback, at least one by Lancer Books, who offered a number of popular titles in inexpensive paperback.

 This latest addition to my collection of Parker Publishing titles, is another book that might qualify as a first-year textbook at Hogwarts. It touches on a broad range of Psychic phenomena, and includes exercises, tips and anecdotes to help a student along. 

The book follows the usual Parker style, which is very readable, and ends each chapter with a series of useful summary points of the chapter. The author's writing style is very clear and readable, almost conversational. She approaches the psychic topics with stories of her personal experiences and fellow experimenters, as well as some references from other authors. She demonstrates a great deal of confidence in what she writes about. She describes herself as a non-conformist, by which she means that she does not adhere too inflexibly to tradition, advising the would-be psychic to avoid being too rigid in their practice, and be open to inspiration (but regular practice is important to improve). 

There's a nice consistency in her philosophy. She opens with spiritualistic subjects, seances and so forth, and then goes on to discuss everything in terms of the energetic "auras" that surround everyone and everything. All subsequent psychic phenomena relate back to either using the energy of one's own aura, or reading the energetic aura of other things or people. 
 

Some of the topics of the book include:

Mediumship & Séances
The Human Aura & Astral Projection
Telepathy & Thought Transference
Premonition & Precognition
Psychokinesis & Telekinesis 
Automatic Writing
Psychometry Powers

Additional subjects covered include reincarnation, spiritualist churches, the use of Ouija boards, and photographic manifestations of the spirit world.

Book Report: Transcendental Meditation by Robert Roth (c)1994

Robert Roth is one of the oldest, most accomplished practitioners and spokesmen of Transcendental Meditation, having trained directly with Maharishi Mahesh Yogi since 1972. He has taught and lectured all around the world, for hundreds of schools, corporations and individuals. 

Transcendental Meditation, created by Maharishi Mahesh Yogi, is probably one of the most famous of the popular schools of meditation, having been made popular by the Beatles and various other Rock Stars and celebrities in the 1960s and 70s. It is apparently a very easy and effective way to reduce stress, improve health and do all those things that Meditation is known for. It apparently is based on the practice of repeating mantras ("mantra yoga").

 The book, unfortunately is very disappointing, basically being a sales pitch for the course, but not offering even a hint of any specifics about the method. Rather, it is simply a collection of anecdotes and testimonials form many many students, along with some scientific research, but by avoiding any specifics it becomes rather repetitive. There is better material on the web, and videos from the Yogi himself on Youtube and elsewhere. 

More info can be found at their website:

Book Report: Mind Control by Emilio Guzman (c)1976


Emelio Guzman appears to be a Mexican experimenter in the field of psychic communication who came across Jose Silva's famous Silva Method mind control course, and became a strong supporter and, we can assume, teacher. This book is his English translation of his original 1972 Spanish title, Control Mental. 

This book is an introduction to the methodology behind The Silva Method. Back in the 1970s, The Silva Method, was a very, very popular discipline, taught all over the world in week-long seminars, variously known as Silva Method, Silva Mind Control and Silva ESP. 

Through a series of meditation techniques similar to self hypnosis, the students learned how to live a more stress-free life, how to improve their thinking skills and day-to-day activities and even how to develop their ESP skills. The courses are still being taught. 

This book is a discussion of the science and methodology behind the Silva method, and a number of the areas that the Method claims to be able to improve. It also touches on some of the specific techniques, but isn't a study guide. I guess you have to take the course, in person or one of their recorded courses, to learn the specifics.

Book Report: Threshholds of the Mind By Bill Harris (C) 2003


 Bill Harris is the originator of Centerpointe Research Institute, famous for their Holosync(c) binaural beat recordings for self improvement and development. He is a pioneer of the Binaural beat technology. He was heavily involved in various forms of meditation and self development before exploring the technology of frequency entertainment.  

 If you're curious about binaural beats and entertainment technology, you'll enjoy this book by one if it's pioneer developers. 

The book explains the technology behind the very successful Holosync recordings, which primarily employ binaural beats to stimulate frequency entrainment, in order to achieve deeper mental states very quickly and reliably. 

Deeper meditative states cause the mind to run at different frequencies. Excited mental states run at a higher frequency, meditative and hypnotic states are much slower (these are commonly referred to as Alpha, Beta, Gamma, Delta, Theta).

Frequency entertainment is the effect whereby an external frequency, like music, can have an effect of our consciousness, and if you've ever experienced loud, pounding dance music, or calming, slow lullabyes, you've experienced the entrainment effect. 

Binaural beat technology is an interesting effect whereby different, specific tones are played into each ear, and the way they interact with each other withing the listener's hearing generates the desired tone. This has proven to be very effective and the result is that the listener can achieve meditative states that normally take meditators a long time to achieve. 

The recordings combine this technology with guided meditations or self help techniques to achieve reliable results. 

 The book is part sales pitch, with lots of testimonials and selling points, part biography and still presents a lot of detailed information about the technology behind the recordings. His personal journey in exploring and developing his materials is as interesting as the science. It offers a lot of practical discussion and techniques for helping one get in control of their thoughts and feelings, whether or not you go in for their products.

Book Report: Sorcery by J. Finley Hurley (C) 1985

Imagine an experienced scientist putting aside any professional biases and exploring the idea that people can influence each other and their surroundings through thoughts (more or less) thought alone, analyzing every step of the process in a scientific method and weighing it against established researcher and observations. Well, that's the book we have here.

You'll probably have noticed a lot of books about metaphysical abilities in the book report section of my blog. What makes this one different is that the author is a clinical psychologist and this book is his analysis of "magical powers" through the lens of scientific data and empirical case studies. And he claims to have based it on his own observations and research.

Since "sorcery" can mean a lot of things to a lot of people, it's worthwhile to clarify that the author's focus is primarily telepathy and it's ability to influence people with or without their knowledge, and he also touches on other cases where practitioners seemed to be able to influence people and events in seemingly magical ways. 

Happily, Hurley is a fun and engaging author, and because he also writes as a scientist, he backs up his observation and hypotheses with some kind of scientific reference (at least enough to satisfy himself). This is pretty unique for this kind of book and also very practical for anyone who wants to delve into the research instead of just taking the author's work for it.

The author hypothesizes that the other-than-rational effects of "Sorcery" cannot be justified by the conscious, rational mind and so must originate in the subconscious, which he terms "Cthonic" mind.

He begins with the well researched phenomena of The Placebo Effect, an often observed phenomena where an inert drug or treatment has a demonstrable effect on a patient simply because of the patient's belief in the outcome or had faith in the healer. He also includes the somewhat more controversial Pygmalion Effect, which suggests that the healer's belief in the placebo is as important or more important than the patient's belief. He cites situations where the placebo effect has been used to heal people, and also to curse them. In the author's view, telepathy is the vehicle whereby a sorcerer's influence is most commonly carried, and he quotes many studies that explore different forms of telepathy.  

This book falls short of offering an illustrated blueprint to practice from, but adventurers will find plenty of inspiration to work with in this tome.

 The biggest problem with this particular book is how hard it is to find. When copies do show up on the market, they usually cost several hundred dollars, and in an interview the author admits that even he doesn't own a copy. Fortunately, PDFs do float around the web, and you should be able to find one with a quick search.

Wise Word About Hypnotism and Politics from the Father of MkUltra

Professor George Estabrooks is known mostly by reputation for being the hypnotic mastermind who conceived of some of the more disquieting things to come out of the Cold War, like MK Ultra and the Manchurian Candidate. But he was first and foremost a scientist, and was equally concerned with the inexplicable way dictators could turn sensible people into fanatics, and he wrote at length about it in his book “Hypnotism” (revised 1957, E.P.Dutton). This excerpt is WELL worth a read, and maybe a little self-reflection:

“How can we guarantee that our choice at the polls will be a wise one? Our previous discussion of hypnotism and mob psychology should help. Is this man you listened to on TV last night a genuine leader or is he a rabble rouser? Is he heading a battle of democratic principles or “a battle of the gravy bowl’? We may safely say that, in America, we have the world’s most intelligent electorate and that, on the whole, our politicians are a superior group, so we are not crying panic. On the other hand, as we have said, “when you stop being better, you stop being good,” and on this matter of electing a potential dictator, you will make that mistake once only. From then on, he will take care that your mistakes are always in his favor.

So play a little game with yourself. Sit down and think over that last spellbinder you heard on the platform, over the radio or on television. Behind every argument is someone’s ignorance. You probably are either for him or against him. Why? 

Was he appealing largely to your reason or was his appeal largely to your emotions?—especially on such matters as class privilege, the race issue, religious issues. These matters can be handled along the lines of reason, but the temptation to go over to the highly emotional appeal is very marked. In other words, were you listening to a man of reason or to a hypnotist who aimed to limit your field of consciousness? [earlier in the book, the author explains the hypnotic state as one where the subject is led to be hyperfocused on a single topic] You say you cannot be hypnotized against your will. Perhaps you were hypnotized last night as you listened to that political address over your TV. It might be well to give a little thought to this matter. Don’t worry about the hypnotist in his laboratory. You will probably never meet him. The most dangerous hypnotist may be the man you listened to last week over the radio. You were his subject. His appeal was emotional, inflammatory, an excellent example of prestige suggestion [“Prestige” refers to a kind of authoritarian hypnotic influence, and eliciting strong emotion as a way to create an altered state]. You came away determined that something drastic should be done – on, shall we say, the racial issue. As a matter of fact, you were a very excellent subject. Think it over.

And think about the nature of that kind of hypnotist. He may be, he often is, a man of great intelligence. You may have your own opinions about Hitler, Mussolini or Napoleon, but no one ever accused them of being morons. They could and did use the brains they had with great effect. Their outlook was purely selfish. They used their intelligence to further their own ends. But Hitler was excellent within these narrow limits.”

If you want a concrete example of this "mass hypnosis" effect, consider that in the year following the 1973 movie, "The Exorcist," there was an explosion of people believing they were possessed that persisted for years afterwards. Even during the movie, people passed out, vomited, and supposedly there were even a few heart attacks. But all those people did was sit down in a theater for an hour or so.

Book Report: Science of Breath by Yogi Ramacharaka (William Walker Atkinson) (C) 1904

 Background Information: The Publisher, The Yogi Publication Society is a press started by William Walker Atkinson at the turn of the 20tdh century to promote his writings on "New Thought," which was the New Age movement of the time. Atkinson himself was quite a character. He was a prolific writer, with over 150 books to his credit, often under any of several pen names. He rose to prominence at the beginning of the 20th century, but seems to have become forgotten in the following decades, though he and the Yogi Publication books are experiencing a new renaissance at the beginning of the 21 century.
Many of the books were written by Atkinson, but they also published other prominent metaphysical works by other authors. The company has changed hands a number of times, so many that the original history was lost to the current owners, but the books are still in print, and still inspiring spiritual seekers.
The author of this book, Yogi Ramacharaka, was one of William Walker Atkinson's many pen names.

This little book (88 pages) is a classic! Despite being over 100 years old, the breathing exercises it offers are easy to practice and very practical. Beginning at the beginning, it thoroughly discusses the western concept of breath and the Eastern concept and why they're important. Of course there's a discussion of Prana, the Hindu word for the metaphysical energy (AKA Chi, or Ki) that is cultivated both through breath and also through meditation, All these chapters are concise and short and they're followed by both basic and additional exercises.
Specifically, you'll discover the Complete Yogi Breath, The Seven Yogi Developing Exercises, Seven Minor Yogi Exercises, Vibrational Breathing, and some other things you can practice as well. There are techniques to use breath and imagery to empower your meditation, health and visualization. 

No New Thought book would be complete without some psychic phenomena exercises and this book includes those as well, so if you want some basic practiced in Thought Projection, Psychic Healing, Charging your Aura and discovering your higher self, that's included too.

Breathing practice is often taught as part of Yoga or Meditation teaching, but it can be practiced all by itself to improve your health and concentration. The book is over 100 years old, so it's no longer protected by copyright. As such, there are a lot of versions available published by a lot of different sources, from the blue hardcover published by Yogi Publication Society, to various paperback versions and even downloadable PDFs that can be found on line. It's well worth a read, and a practical addition to anyone's metaphysical or physical culture book collection.

Book Report: Clinical Hypnosis by Crasilneck and Hall (c) 1985

 Harold Crasilneck and James A Hall were accomplished clinical hypnotherapists and psychologists who worked extensively in the medical arena. Crasilneck was noted for his work with hypnosis in pain control and Hall was a Jungian psychologist. Together they worked and researched in way that hypnosis can be employed in the medical arena. 

 This book is a more academic textbook than many of the books I've reviewed on this blog, but i think it's a valuable read for serious hypnotists. 

The book is dry and factually dense like many academic works. Through it's many chapters, it touches on valuable applications of hypnosis in many different medical and psychological situations. Each chapter is replete with a great number of footnotes and research references. 

Having been written in 1985, I imagine that most of the research material has been superseded by more advanced knowledge by now, but the sheer number of different clinical applications that they have actual experience and data on is both inspiring and practical. You won't find much technique described, so it's really appropriate for a more advanced practitioner, but it will tickle your imagination as to how far hypnosis can actually benefit people. 

Personally, I also found it interesting to read about hypnosis as described from a psychologist's perspective. Their analysis of some situations, as well as the terminology they use was a very interesting comparison to my training.

Body Mass Index --Is the BMI For Real, or is the B for Baloney?


The Controversy:

The Body Mass Index is a common graph used for determining what a patient’s “normal” weight should be, based on their weight and height. Nevertheless, some have claimed it to be outdated, unscientific, inaccurate and even racist. Yet many doctors and weight loss authorities still use it and feel it is reliable. What is it and is it accurate?

 I recently had a visit with my new doctor. Some people dread going to the doctor, but I’ve always looked forward to it. I’m generally pretty healthy. I used to be an athlete, and I still try to keep in pretty good shape. Not great, but pretty good, and usually a little better than my age bracket. A visit to the doctor is normally uneventful, and sometimes even complementary. (Full disclosure: I carry a bit more belly fat than I’d like to, which I credit to years of working long hours, and I’ve got a touch of osteoarthritis from an old car injury). When the COVID lockdown ended, I started hitting the gym nearly every day for an hour or two, and I put on a good bit of muscle, even if I didn't burn much fat.

 I wasn’t surprised when the doctor told me, “You have to lose weight!” In fact, I heartily agreed, “I know! After a year in lockdown I could certainly stand to lose about 20 pounds.”

 “NO! You have to lose 50 pounds! You’re almost morbidly obese!”

 Obese?! For once, I was at a loss for words. Was he even looking at me? There was no one else in the room, but what he was saying didn’t make sense. I’m not a terribly large person, I’m only 5 foot 5”. Twenty pounds lighter and I’d look pretty good. 25 pounds would be pushing it a bit, but FIFTY POUNDS? I’d look like skeleton. Sure I’m a bit chubby, but obese? Morbidly obese?!  

 “It’s THE BMI! BODY MASS INDEX!” he snapped, “It’s your body composition!”

 I thought quickly. “Are you looking at the scale for women, maybe?” I asked, even though he was quoting out of his head. He told me it was the same for men and women. The only factors to consider, he said, were weight and height, but that didn’t make any sense to me. A woman my height might reasonably be much lighter than I am, if she had delicate bone structure and very little muscle or fat. Aside from my spare tire, I’d added enough muscle to my chest and shoulders since the COVID lockdown that the new jacket I bought only a year ago didn’t fit over my shoulders anymore.

At this point, red flags were going up in my mind. I’d never had a doctor say anything like this to me before, and for me, his judgement was coming into question, because what he was saying didn't sound scientific. “You know muscle is heavier than fat?” I felt compelled to ask. He insisted that it didn’t matter. It was all the same, he said, only height and weight mattered. I was flummoxed. 

As far as he was concerned, there was no more to discuss. BMI was everything there was. All of this shook my faith in the doctor, but maybe he was right and I was wrong. He was the doctor after all. Could I actually be the thinnest obese man in history?

As I left the office, I suppressed the urge to eat an entire pizza in protest, and decided to learn a bit about the BMI when I got home.

I Have to Educate Myself
As a motivational coach, I’ve dealt with a lot of weight loss clients. I deal with their feelings and motivations, but I leave the technicalities of weight and diet to their health care professionals. I can help the clients get over their mental and emotional hurdles, but I don’t tell them what goals to reach for. So I knew about the Body Mass Index (BMI), but I didn’t know the specifics.

What little I did know was that the very concept of “body composition” is the ratio of muscle to non-muscle tissue, and for practical purposes of weight loss, what mattered was the percentage of fat versus non-fat, and it’s common knowledge that muscle weighs more than fat of the same volume.

I also knew there were other variables involved. Gender matters. Males tend to have denser bone and muscle than females as a result of hormonal changes at puberty. Another thing to be considered is age. A 20-year old is usually going to have a stronger metabolism and naturally fitter body than a 40-year old, even if the 40 year old exercises a whole lot more, and I’m 60! (I don’t look a day over 58, though). Race and genetics are another issue that has to be factored in. Different ethnicities store fat in different ways and in different parts of the body, and may not offer the same weight/height ratios.There are probably other specific variables as well.


There it is, the BMI chart. And sure enough, It says I’m vastly overweight. But you know what? It might say you’re overweight too! You’ll notice there’s no accounting for any of those other, obvious, variables. I thought there might be a more sophisticated version of the chart and searched for it on the web, but there aren’t any. Maybe the doctor was right, but to my mind, simple common sense says this chart is both incorrect and also unscientific--two variables, height and weight, simply aren’t enough to accurately gauge a person’s health. 

It didn’t take me long to discover a whole lot more. There’s a lot of material about the BMI available, but it wasn’t the dry science I was expecting.

The Quetelet Scale
Are you Belgian? Are you more than 150 years old? If you answered “no” to these questions, the the BMI may not be right for you!

The BMI, was originally known as The Quetelet Scale, after it’s creator was Lambert Adolphe Jacques Quetelet (1796-1874). Quetelet was possessed of one of those brilliant, inquisitive, scientific minds which this period in history produced so many of. He focused his considerable mental powers on many aspects of the natural sciences and the arts, but his two greatest passions were astronomy and mathematics. Stars aside, He felt that numerical statistics could capture and describe the idealized perfection of nature (which he believed to be graphed as a bell curve). He further felt that once that mathematical ideal was established from a small pool of data, it could be generalized out reliably to a much larger population. To that end, he compiled statistics on all kinds of things, including crime rates, marriage rates and, since he was artistically inclined, perfect human proportions. He came up with the formula for the ideal human body based on the formula: weight x height2. In other words,  'the weight increases as the square of the height' This formula was based on measurements from the humans he happened to have at hand, and is sort of the way you's measure the volume of a milk bottle. He published his findings in 1830, and the numbers have not been revised since. 

He was not a doctor. He didn’t know much about medical or structural variations or about human anatomy, and he didn’t intend the Quetelet Scale to be a diagnostic tool. It was more of a philosophical exercise.

The Quetelet Scale enters a New Century
Ancel Benjamin Keys (1904 – 2004) was another brilliant scientist of a different century, and a trailblazer in the field of nutrition. We can credit him for the our modern understanding of the relationship of cholesterol to heart disease, the benefits of the Mediterranean diet, and a number of other discoveries which have become the cornerstones of modern nutritional science. He helped formulate special meals for the soldiers in WW2 based on their caloric needs and it’s rumored the (in)famous K-Ration of WW2 got the “K” in Keys’ honor. 

One of his grandest research projects was the Seven Country Study, which charted the relationship of diet and longevity (particularly heart disease) in seven different countries over a period of several decades. He followed the health histories and measurements of hundreds, possibly thousands, of people over the years in order to get a large sampling of data. In order to process and quantify all the data he was collecting, he chose the Quetelet scale out of convenience, because out of all the existing scales for body mass, he felt the Quetelet Scale was mathematically the most complete, and therefor, convenient for his purposes. When he published some of his findings in 1972, he included the Quetelet Scale, which he renamed The Body Mass Index. But he was clear that it was really only useful for processing large amounts of demographic data, not for use on individuals. 

Today
So there we have it. An academic exercise conducted by Belgian astronomer nearly 200 years ago in the search for mathematical perfection, picked up in 1972 as a convenient demographic tool. It does not figure things like muscle vs. fat, activity level, age, gender, nutrition habits or an individual’s genetic variations. It simply calculates the volume of a human body as if it’s a jam jar. 

So why on earth would modern doctors today, people of science, take up this bit of outdated ephemera when modern tools and methods could provide better data? To be fair, a lot of medical experts neither use nor endorse it. Many have come up with better alternatives. Yet some doctors have accepted it without questioning it’s obvious flaws. Many sources on the internet present it as simple fact without any discussion of it’s failings. According to what I’ve been able to glean, many medical schools are still teaching it, and the students are accepting and absorbing it (even though their own eyes are probably giving them contradictory data!). So why would medical schools promote something that one’s own sense contradicts?

I don’t know. According to some of the sources below, the BMI was picked up and endorsed not by medical experts, but by health insurance companies who felt is assessed the health risks of their customers accurately (and with a good safety margin for the company, I’d imagine). Apparently, a lot of people who teach it never even thought to question it. It’s just been passed along by tradition.  

Are There Better Ways To Measure Fat?
If you want to get an accurate gauge of your weight and health, it goes without saying that you should consult with a health care professional who is trained and qualified. They will know the best course of action for you regarding testing, and for helping you reach your own health and fitness goals.

 There are a number other more thorough body mass indices. One that attempts to address the shortcomings of the BMI is the ABSI (A Body Shape Index). The ABSI was created at City College of New York, with an initial pool of test subjects that included over 14,000 people, and it has since been reaffirmed with even larger sample groups. It is still a generalization, but at least it includes more of the obvious, important variables: age, gender, waist diameter as well as height and weight. If more exacting tests are needed, there are a number of them. I’ve listed the common ones below.

Body Composition Testing Methods
Skinfold Caliper Test-- This is a very common test with athletes and body builders, and is considered to be an easy and fairly accurate test for measuring subcutaneous (beneath the skin) fat. It uses a special caliper which pinches the skin in several specific places around the body to measure the thickness of the fat underneath. The thicker the pinch, the more fat. These measurements are then calculated to get an overall average. It can also indicate which parts of the body have the most or least fat stored in them (which can be an important finding in certain situations). There are several obvious shortcomings of this test. It can’t measure fat stored deep inside the body, only under the skin. It can also be inaccurate if too much or too little pressure is applied with the calipers, or if the pinch is too big or too small. Individuals may also have more or less dense skin, regardless of the fat beneath.  

Bioelectric Impedance Analysis-- This utilizes a device that sends an imperceptible electric current through the body, and measures the amount of electrical resistance the body offers. Since fat has a greater electrical resistance than muscle or water, measuring the resistance will tell how much fat is conducting the current. For the test, several electrodes are attached to various parts of the body. The test itself can be done fairly quickly. Some sources feel it’s reliability is questionable, just because there are so many things that can potentially throw off the results--exercising before the test, dehydration, skin temperature, room temperature, medication, etc. Nevertheless its fast and convenient and a good starting point. There are even home devices you can hold between your hands, although their accuracy seems questionable. 

Hydrostatic Weight Measurement--  This is also considered a very accurate measurement of body composition, though some sources indicate it’s considered a bit old fashioned, perhaps due to the complexity of test. An individual’s weight is measured before the test (dry), and then the individual is submerged in a tank of water and weighed again. The theory behind it is that fat is more buoyant than non-fat, so the individual will weight less when submerged. By noting the difference between the wet and dry weight, they can get a pretty accurate measurement of the actual amount of fat by weight.

Dual-energy X-ray Absorptiometry (DXA or DEXA)-- This involves a special scanner that creates an X-ray imaging of the entire body that also measures the density of the various structures--bones, organs, fat and muscle. This is obviously an extremely accurate way of measuring and seeing the fat in different places, and it can also measure density of bones and other organs. It generally takes about 15 minute or less to do.

Thoughts About The Other Controversial Points
In fairness, the BMI isn’t entirely inaccurate, either. It was based on measurements taken from “average” (not physically active) 19th century Belgian men, who tended to be somewhat smaller, and lighter due to the their diet and living conditions. So while modern 20-21st century American and European people across the board are a bit bigger and heavier, the BMI does seem to be more accurate with younger, less physically active women (physical activity tends to add muscle mass and throw off the accuracy).

A number of sources (including a few of the links cited below) state the BMI to be “racist.” By now we’ve established it isn’t a reliable index for any other group except 200 year old Belgians. I don’t know if Quetelet even knew that different human genetic groups had different anatomical specifics, but most likely, he didn’t know or consider it. He wasn’t a medical man. However it’s fair to say it’s application by modern medicine to a broad range of race and body types is, at least, misguided.

When I was discussing this with someone, they asked why the gender discussion is only in terms of male and female and ignores more of the gender variations that are accepted in the 21 century. I have no answer to that, since I didn’t find any data about that. I imagine that this is why it’s important to have qualified professionals interpret the data, and that we’ll see more variation in the future.
