An entheogen ("generating the divine within")[4] is a chemical substance used in a religious, shamanic, or spiritual context that may be synthesized or obtained from natural species. The chemical induces altered states of consciousness, psychological or physiological (e.g. bullet ant venom used by the Satere-Mawe people). Entheogens can supplement many diverse practices for transcendence, and revelation, including meditation, yoga, and prayer, psychedelic and visionary art, chanting, and music including peyote song and psytrance, traditional medicine and psychedelic therapy, witchcraft, magic, and psychonautics.
