Entheogen

Entheogens are psychedelic drugs—and sometimes certain other psychoactive substances—used for engendering spiritual development or otherwise in sacred contexts. They have been used in various ways, e.g., as part of established religious rituals or as aids for personal spiritual development ("plant teachers"). Anthropological study has established that entheogens are used for religious, magical, shamanic, or spiritual purposes in many parts of the world. Entheogens have traditionally been used to supplement many diverse practices geared towards achieving transcendence, including healing, divination, meditation, yoga, sensory deprivation, asceticism, prayer, trance, rituals, chanting, imitation of sounds, hymns like peyote songs, drumming, and ecstatic dance. The psychedelic experience is often compared to non-ordinary forms of consciousness such as those experienced in meditation, near-death experiences, and mystical experiences. Ego dissolution is often described as a key feature of the psychedelic experience.
