Tom Kenyon, a psychologist and musician, has spent years studying the effects of sound, music, and language on the human nervous system. Kenyon offers a technical excursion into how the brain works, noting the clear distinction between brain and mind. To do this he ascends to the heavens with Pegasus and drops by a shopping mall to visit an amoeba. Through Kenyon's book, the reader will learn to overcome test anxiety, increase intelligence, power athletic abilities, hone language skills, cure numerous psychological problems, tweak creativity, and jump into altered states of consciousness.
My mother came across this book in the 90s and claims it is still one of her favorite reads. The copy I read I got from my brother; the sticker from eastern Oregon correctional institution is still on it (there's a nice irony there).
Anyhow. I'm going to start by saying I think this is a worthwhile read even though by now, it's outdated. There are some basic breathing techniques I have incorporated into my daily life. There are some more exercises described that I would like to try and I'll use this as my reference. There's yet a third category: exercises I would try only with a willing guide or partner. Some of this stuff- consciousness expanding and deep meditative work- can overall be isolating.
If you want to dip your toe in the water to play with some "radical" concepts or start to 'treat' yourself in a new way, this book is provocative and can help you. Surrender.
