The Psychedelic Experience: A Manual Based on the Tibetan Book of the Dead - Penguin Modern Classics by Timothy Leary, Ralph Metzner

"The Psychedelic Experience", created by the prophetic shaman-professors Timothy Leary, Ralph Metzer and Richard Alpert, is a foundational text that serves as a model and a guide for all subsequent mind-expanding inquiries. In this wholly unique book, the authors provide an interpretation of an ancient sacred manuscript, the "Tibetan Book of the Dead", from a psychedelic perspective. "The Psychedelic Experience" describes their discoveries in broadening spiritual consciousness through a combination of Tibetan mediation techniques and psychotropic substances.
