Created by the prophetic shaman-professors Timothy Leary, Ralph Metzner, and Richard Alpert (Ram Dass), this foundational text serves as a model and a guide for all mind-expanding inquiries. Based on a unique interpretation of The Tibetan Book of the Dead, The Psychedelic Experience remains a vital testament to broadening spiritual consciousness through a combination of Tibetan meditation techniques and psychotropic substances. More than fifty years after the Summer of Love, the promise of the psychoactive '60s-that deeper self-awareness and greater harmony can be achieved through reality-bending substances and practices-is close to becoming a mainstream phenomenon. The signs are everywhere, from a renewed interest in the therapeutic effects of LSD and micro-dosing, to the popularity of the ayahuasca trips and the annual spectacle of Burning Man. Now, for a new generation seeking the trip of a lifetime, The Psychedelic Experience is the essential guidebook to getting there. The updated edition includes a dedication to Aldous Huxley with a short introductory citation from Huxley's book The Doors of Perception, which was used by the Beatles in the song Tomorrow Never Knows and a brand-new introduction by Daniel Pinchbeck, author of Breaking Open the Head: A Psychedelic Journey into the Heart of Contemporary Shamanism. "It is a book for the living as well as for the dying." -Lama Govinda, founder of the Arya Maitreya Mandala
