This book describes a new model for trance as well as practical techniques to analyse and design trances. Trance is used consciously and unconsciously not only by psychologists, therapists and hypnotists, but also yogis, priests, magicians, witches, advertisers, politicians, lawyers, addicts and psychotics. Writing from his personal experience, Wier suggests that some of these ideas might represent new practical precision tools for psychologists as well as for those who work with the occult. Practical suggestions for meditators, yogis, witches and others are included to deepen trance and to increase the depth as well as terminating trance. Pathological trance and trance abuse are also described with suggestion on how they may be recognized and prevented.
