The Psychedelic Experience, created in the movement's early years by the prophetic shaman-professors Timothy Leary, Ralph Metzner, and Richard Alpert (Ram Dass), 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 meditation techniques and psychotropic substances. As enlightening as the text it reflects, The Psychedelic Experience is a guidebook to the wilderness of mind and an indispensable resource from the founding fathers of psychedelia. This edition includes the 2007 introduction by Daniel Pinchbeck, author of 2012- The Return of Quetzalcoatl and Breaking Open the Head.
