We are in the midst of a powerful psychedelic renaissance. After four decades of hibernation, the promise of the psychoactive ’60s—that deeper self-awareness, achieved through reality-bending substances and practices, will lead to greater external harmony—is again gaining a major following. The signs are everywhere, from the influence of today’s preeminent psychedelic thinker Daniel Pinchbeck, to the renewed interest in the legacy of Terence McKenna, and to the upsurge of collective, inclusive (and overtly tripped-out) cultural phenomena like the spectacle of Burning Man.

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 sacred 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 manual uses material from The Tibetan Book of the Dead for this preparation. The authors also make an important contribution to the interpretation of The Tibetan Book of the Dead. They show that it is concerned not with the dead, but with the living. The last section of the manual provides instructions for an actual psychedelic session, under adequate safeguards.

The authors were engaged in a program of experiments with LSD and other psychedelic drugs at Harvard University until sensational national publicity unfairly concentrating on student interest in the drugs, led to the suspension of the experiments. Since then, the authors have continued their work without academic auspices.

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 DeadThe 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.

Timothy Leary was one of the most famous countercultural icons of the 1960s. In 1957, the Harvard psychologist experienced a "profound transcendent experience" while taking hallucinogens in Mexico. No longer content with his work in personality assessment, Leary began advocating the psychotherapeutic and spiritual benefits of LSD. His experiments with LSD often involved students and wild "tripping" parties, which eventually led to his dismissal from Harvard. With patronage from heirs of the Mellon fortune, Leary continued his experiments and prolific writing career at a rambling estate in upstate New York known as Millbrook. In 1967, Leary spoke at a San Francisco "Be-In," where he coined the phrase "Turn on, tune in, and drop out." Labeled "The Most Dangerous Man in America," Leary had many run-ins with the law and served several prison sentences. He died of prostate cancer in 1996; the following year seven grams of his ashes were launched into space aboard a Pegasus rocket.



Ralph Metzner, Ph.D., was a psychologist who explored states of consciousness and transformational practices throughout his career. As a graduate student at Harvard (where he received a Ph.D. in clinical psychology), he worked with Timothy Leary and Richard Alpert (later Ram Dass) on the Harvard Psilocybin Projects. He co-wrote The Psychedelic Experience and was editor of The Psychedelic Review. He was a professor of psychology at the California Institute of Integral Studies. He was also president of the Green Earth Foundation, a non-profit organization dedicated to reconnecting humans and the environment. The author of over a dozen books, Dr. Metzner maintained a part-time psychotherapy practice and conducted numerous workshops on consciousness transformation, both nationally and internationally.



Ram Dass served on the faculty at Stanford and Harvard Universities. In the 1960s, he traveled to India, where he met his guru, and over the course of his life pursued a variety of spiritual practices, including guru kripa, devotional yoga, karma yoga, many forms of meditation, and Sufi and Jewish studies. Many of his books, including Be Here Now, are international bestsellers and classics of their kind. He died in December 2019.
