We've all wondered - about hypnosis, meditation, dreams and ghosts. What's it all about? This book offers a fresh view of the whole range of trance experiences and presents a vital key for their understanding. The author examines why science has not succeeded in this area and he presents scientific arguments giving purpose to trance states. By reasoning that all these states of mind have a common root, and should be examined as a group, much more meaning is given to the terms hypnosis, meditation, hallucination, faith healing, speaking in tongues, mystical experience and many more intermediate states. It is shown that the evolved system of instinctive trance is the same mental state that produces non-instinctive trance, being either spontaneous or induced as in hypnosis or meditation. In deep trance we sometimes experience ecstatic enlightenment that can be either religious or secular. An in-depth study of telepathy, and the way it is related to biology, has revealed a likely explanation as to HOW and WHY we occasionally experience telepathy.
