The Doors of Perception The Classic Exploration of Altered Consciousness and Spirituality

In this essay, first published in 1954, Huxley describes taking mescaline under medical supervision and recording what he saw and felt. Ordinary things such as a chair, a vase of flowers or the folds of trousers seemed filled with striking colour and meaning. He reflects on how the mind normally filters experience, and compares his state with mystical traditions and with the world of art. The tone is calm, curious and personal. The book shaped later conversations about consciousness, spirituality and drugs, and remains a thoughtful first-hand account.
