Stanislav Grof's first 17 years of research into the non-ordinary states of consciousness induced by LSD and other psychedelics led to a revolutionary understanding of the human psyche. His research was the impetus behind a vastly expanded cartography of the unconscious, including two new realms still unacknowledged by official academic circles the perinatal domain, which holds memories of the various stages of birth and the transpersonal domain which mediates experiential identification with other species and mythic figures, visits archetypal realms, accesses past life memories and unites with the cosmic creative principle.The research presented in this book provides a map of the psyche that is essential for understanding such phenomena as shamanism and near-death experiences as well as other extraordinary states of consciousness. This map has led to the development of important new therapies in psychiatry and psychology for treating mental conditions often seen as disease and, therefore, suppressed by medication. It, also, provides a new threshold to understanding and entering the numinous realm of the spirit.This is a new edition of Realms of the Human Consciousness.
