The Psychedelic Experience: A Manual Based on the Tibetan Book of the Dead. Timothy Leary, Ralph Metzner, Richard Alpert (Penguin Modern Classics)

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.
