After completing his groundbreaking research chronicled in DMT: The Spirit Molecule, Rick Strassman was left with one fundamental question: What does it mean that DMT, a simple chemical naturally found in all of our bodies, instantaneously opens us to an interactive spirit world that feels more real than our own world? When his decades of clinical psychiatric research and Buddhist practice were unable to provide answers to this question, Strassman began searching for a more resonant spiritual model.

From 1990 to 1995 Dr. Rick Strassman conducted U.S. Government-approved and funded clinical research at the University of New Mexico in which he injected 60 volunteers with DMT, one of the most powerful psychedelics known. His detailed account of those sessions is an extraordinarily riveting inquiry into the nature of the human mind and the therapeutic potential of psychedelics. DMT, a plant-derived chemical found in the psychedelic Amazon brew, ayahuasca, is also manufactured by the human brain. In Strassman's volunteers, it consistently produced near-death and mystical experiences.

Less than 50,000 years ago mankind had no art, no religion, no sophisticated symbolism, no innovative thinking. Then, in a dramatic and electrifying change, described by scientists as "the greatest riddle in human history," all the skills and qualities that we value most highly in ourselves appeared already fully formed, as though bestowed on us by hidden powers. In Visionary, Graham Hancock sets out to investigate this mysterious "before-and-after moment" and to discover the truth about the influences that gave birth to modern human mind.

Whitley Strieber and Jeffrey J. Kripal team up on this unprecedented and intellectually vibrant new framing of inexplicable events and experiences. Rather than merely document the anomalous, these authors - one the man who popularized alien abduction and the other a renowned scholar - deliver a fast-paced and exhilarating study of why the supernatural is neither fantasy nor fiction but a vital and authentic aspect of life.

The so-called Tibetan Book of the Dead has been renowned for centuries as a cornerstone of Buddhist wisdom and religious thought. More recently, it has become highly influential in the Western world for its psychological insights into the processes of death and dying - and what they can teach us about the ways we live our lives. It has also been found to be helpful in the grieving process by people who have recently lost their loved ones. This authoritative translation preserves the form and spirit of the original and was prepared especially for Western audiences.
