Years after the Summer of Love, the promise of the psychoactive 1960s—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 to the popularity of ayahuasca trips and the annual spectacle of Burning Man.

The Psychedelic Experience, created 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. 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.

For a new generation seeking the trip of a lifetime, The Psychedelic Experience is the essential guidebook to getting there.
