WITH A FORWARD BY J. G. BALLARD In 1953 in the presence of an investigator Aldous Huxley took four-tenths of a gramme of mescalin sat down & waited to see what would happen. When he opened his eyes everything from the flowers in a vase to the creases in his trousers was transformed. Huxley described his experience with breathtaking immediacy in The Doors of Perception. In its sequel Heaven & Hell he goes on to explore the history & nature of mysticism. Still bristling with a sense of excitement & discovery these illuminating & influential writings remain the most fascinating account of the visionary experience ever written.
