The word "entheogen" literally means "generating the divine within". In its strictest sense the term refers to a psychoactive plant or substance that occasions enlightening spiritual or mystical experience, within the parameters of a cult, in the original sense of cultus. In a broader sense, the word "entheogen" refers to artificial as well as natural substances that induce alterations of consciousness similar to those documented for ritual ingestion of traditional shamanic inebriants.
