Hypnosis is a technique that has been used for centuries. It is one of the most strangely powerful tools of mental control and manipulation, and has historically had occult connotations. However, it is a well-proven practice, with many scientific and therapeutic applications for those who master its mysteries.
it's a short read and sort of a good introduction to hypnosis i think i remember, but i also remember he had some of his own personal theories on subconscious that were quite interesting. one of the better reads on hypnosis i have read.
