Dr. Grof began his research into the psychotherapeutic uses of LSD in 1960 at the Psychiatric Research Institute in Prague, Czechoslovakia. More than thirty years of work in this field make him eminently qualified to write this book. He is the founding president of the International Transpersonal Association, and has taught and lectured in academic and workshop settings worldwide. Dr. Grof is the author of numerous other books, the latest of which is Psychology of the Future: Lessons from Modern Consciousness Research.
