Altered States of Consciousness

The study of the nature of human consciousness, a dormant and often taboo topic in psychology, is once again being developed into a rich area for scientific inquiry. This is the first book to afford readers the opportunity to explore a wide range of special states of consciousness, both natural and induced with the aid of drugs, yoga and hypnosis. An impressive selection of contributors makes this volume an authoritative source on what is arguably one of the greatest mysteries of life.
