"The Doors of Perception" and "Heaven and Hell"  by Aldous Huxley

"Among the most profound and influential explorations of mind-expanding psychadelic drugs ever written, here are two complete classic books—The Doors of Perception and Heaven and Hell—in which Aldous Huxley, author of Brave New World, reveals the mind's remote frontiers and the unmapped areas of human consciousness. This new edition also features an additional essay, "Drugs That Shape Men's Minds," which is now included for the first time."
