From 1990 to 1995, Dr. Rick Strassman conducted a government-approved and funded clinical research at the University of New Mexico, during which he administered DMT to sixty volunteers, one of the most powerful psychedelic substances. The detailed description of these sessions constitutes an extremely captivating investigation into the nature of the human mind and the therapeutic potential of psychedelics. DMT, a plant-derived chemical compound found in the psychedelic Amazonian brew, ayahuasca, is also produced by the human brain. In Strassman's volunteers, it consistently induced near-death experiences and mystical experiences. Many of them report compelling encounters with intelligent non-human presences, aliens, angels, and spirits. Almost all felt that the sessions were among the most profound experiences of their lives. Strassman's research links DMT with the pineal gland, which is considered by Indians as the site of the seventh chakra and by René Descartes as the seat of the soul. DMT: The Spirit Molecule puts forward the daring position that DMT, naturally released by the pineal gland, facilitates the movement of the soul in and out of the body and is an integral part of birth and death experiences, as well as higher states of meditation and even sexual transcendence. Strassman also believes that "alien abduction experiences" are caused by random releases of DMT. If used wisely, DMT could trigger a remarkable era of scientific exploration in the innermost realms of the human mind and soul.
