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.

Found throughout the plant and animal kingdom, DMT (dimethyltryptamine) is also naturally occurring in humans, and may be released during near-death and actual death experiences, earning it the title “the spirit molecule.” When taken as a psychedelic, either via ayahuasca or in pure form, DMT is experientially considered to be one of the strongest and strangest of all entheogens. The majority of high-dose users report visions of unknown yet curiously familiar alien worlds and encounters with sentient nonhuman presences.

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.

Where did God come from? What do the bible stories really tell us? Who or what was Jesus Christ? This audiobook challenges everything we think we know about the nature of religion.

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.
