The Doors of Perception; Heaven and Hell.

'The Doors of Perception' is a philosophical essay detailing his experiences when taking mescaline. The book takes the form of Huxley's recollection of a mescaline trip that took place over the course of an afternoon in May 1953. The book takes its title from a phrase in William Blake's 1793 poem The Marriage of Heaven and Hell, "If the doors of perception were cleansed, everything would appear to man as it is, infinite." Huxley recalls the insights he experienced, which range from the "purely aesthetic" to "sacramental vision". For biographer David King Dunaway, 'The Doors of Perception', along with 'The Art of Seeing', can be seen as the closest Huxley ever came to autobiographical writing. The book was the influence behind Jim Morrison's naming his band The Doors in 1965. 'Heaven and Hell' is a philosophical essay by Aldous Huxley published in 1956. Huxley derived the title from William Blake's book The Marriage of Heaven and Hell. The essay discusses the relationship between bright, colorful objects, geometric designs, psychoactives, art, and profound experience. Heaven and Hell metaphorically refer to what Huxley conceives to be two contrary mystical experiences that potentially await when one opens the "doors of perception"—not only in a mystical experience, but in prosaic life.
