This is an interesting intro into the phenomena of hypnosis, the author like most(I've read) on the subject begins by dispeling the myths around the subject, introduces the uses, and techniques in applying the techniques, and give a sample suggestion which helped me very much, the book has a couple of success stories as well, i borrowed a friend who prepared a tape using the sample induction techniques which entrancd him whilst reading to the recorder which was entirely funny,
