One of the more exciting scholarly developments of the century to date has been the growth of studies – previously hindered for too long by legal barriers – into mystical experiences induced by psychedelic drugs. In a landmark 2006 experiment, rigorously controlled and double-blind, Roland Griffiths’s research team at Johns Hopkins University found that people given high doses of psilocybin – the active ingredient in magic mushrooms – typically had experiences they described as “having substantial personal meaning and spiritual significance”, and bore several other characteristics in common with a certain kind of non-drug-induced mystical experience: a sense of merging with ultimate reality, a nondual sense of the unity of reality, a sense of awe or sacredness. This sort of mystical experience, it seems, can be chemically induced.
