The theme continues here, which is the subject of Rick Strassman’s book “DMT - the Molecule of the Spirit” (Ves Publishing House, 2010). The experience of expanding consciousness and gaining knowledge of the Universe through the use of psychedelic drugs is examined in various aspects. Rick Strassman writes about the results of a laboratory study he carried out by injecting volunteers with DMT (N,N-dimethyltryptamine). This unique psychedelic is found in plants that alter the state of consciousness, and is also produced by the human brain in critical states (for example, at birth and death). Luis Eduardo Luna and Slawek Wojtowicz turn to South American culture, describing the modern tradition of using hallucinogenic plants in legal religious organizations. Ede Fresca offers a theoretical study, based on the principles of quantum physics, of the phenomenon of travel to other worlds under the influence of psychedelics. The authors of the book - scientists in the field of medicine and the humanities - agree that certain psychedelic drugs, taken under strictly defined conditions and purposes, contribute to the solution psychological problems, provide a unique spiritual experience and expand the picture of existence. A book for those who are interested in human psychology, the nature and diversity of spiritual experience, the existence of other worlds, access to areas of knowledge not yet mastered by modern science.
