 and R. Gordon Wasson). The literal meaning of the word is "that which causes God to be within an individual". The translation "creating the divine within" is sometimes given, but entheogen implies neither that something is created nor that that which is experienced is within the user.

The term is derived from two words of ancient Greek, ἔνθεος (entheos) and γενέσθαι (genesthai). The adjective entheos translates to English as "full of the god, inspired, possessed," and is the root of the English word "enthusiasm." The Greeks used it as a term of praise for poets and other artists. Genesthai means "to come into being." Thus, an entheogen is a substance that causes one to become inspired or to experience feelings of inspiration, often in a religious or "spiritual" manner.

Since the experience originates from an external source, the "divine within" can be illustrated as an absorption or collection of divine, rather than a creation that originates within the person. In other words, an entheogen is something that fills someone with god. Given the broad scope of this statement, it can be argued that the word should be inclusive of substances, objects, and/or experiences beyond psychoactives.

Entheogen was coined as a replacement for the terms hallucinogen and psychedelic

 was celebrating a mushroom velada with pills of Indocybin or synthetic psilocybine.

On the 1962 expedition organized by R. Gordon Wasson to see Maria Sabina, Hofmann came along and brought a bottle of psilocybin pills. Sandoz was marketing them under the brand name "Indocybin" — "indo" for both "Indian" and "indole" (the nucleus of their chemical structures) and "cybin" for the main molecular constituent, "psilocybin." ("Psilo" in Greek means "bald," "cybe" means "head"). Hofmann gave his synthesized teonanacatl to the curandera, who divulged the Indians' secret. "Of course," Wasson recalls of the encounter, "Albert Hofmann is so conservative he always gives too little a dose, and it didn't have any effect." Hofmann had a different interpretation: activation of "the pills, which must dissolve in the stomach before they can be absorbed, takes place after only 30 to 45 minutes, in contrast to the mushrooms, which, when chewed, work faster because part of the drug is absorbed immediately by the mucosa in the mouth." In order to settle her doubts about the pills, more were distributed, bringing the total for Maria Sabina, her daughter, and the shaman Don Aurelio up to 30 mg., a moderately high dose by current standards but not perhaps by the Indians'. At dawn, their Mazatec interpreter reported that Maria Sabina felt there was little difference between the pills and the mushrooms. She thanked Hofmann for the bottle of pills, "saying that she would now be able to serve people even when no mushrooms were available."

s that are naturally occurring in plants, fungi, or animals can be used in an entheogenic context or with enthogenic intent. Since non-psychoactive drugs can also be used in this type of context, the term "entheogen" refers primarily to substances that have been categorized based on their historical use. Toxicity does not affect a substance's inclusion (some can kill humans), nor does effectiveness or potency (if a substance is psychoactive, and it has been used in a historical context, then the required dose has also been found).

Classical mythology and cults

Although entheogens are taboo and most of them are officially prohibited in Christian and Islamic societies, their ubiquity and prominence in the spiritual traditions of various other cultures is unquestioned. "The spirit, for example, need not be chemical, as is the case with the ivy and the olive: and yet the god was felt to be within them; nor need its possession be considered something detrimental, like drugged, hallucinatory, or delusionary: but possibly instead an invitation to knowledge or whatever good the god's spirit had to offer."

 has suggested that the self-revelation and healing abilities attributed to the figure of Jesus may have been associated with the effects of the plant medicines, this evidence is dependent on pre-Septuagint interpretation of Torah and Tenach. Allegro was the only non-Catholic appointed to the position of translating the Dead Sea scrolls. His extrapolations are often the object of scorn due to Allegro's non-mainstream theory of Jesus as a mythological personification of the essence of a "psychoactive sacrament". Furthermore, they conflict with the position of the Catholic Church with regard to transubstantiation

The historical picture portrayed by the Entheos journal is of fairly widespread use of visionary plants in early Christianity and the surrounding culture, with a gradual reduction of use of entheogens in Christianity. R. Gordon Wasson's book Soma prints a letter from art historian Erwin Panofsky asserting that art scholars are aware of many 'mushroom trees' in Christian art.

The question of the extent of visionary plant use throughout the history of Christian practice has barely been considered yet by academic or independent scholars. The question of whether visionary plants were used in pre-Theodosius Christianity is distinct from evidence that indicates the extent to which visionary plants were utilized or forgotten in later Christianity, including so-called "heretical" or "quasi-" Christian groups, and the question of other groups such as elites or laity within "orthodox" Catholic practice.

Cultural use

Entheogens have been used in various ways, including as part of established religions, secularly for personal spiritual development as tools (or "plant teachers") to augment the mind, secularly as recreational drugs, and for medical and therapeutic use.
