One spring morning in 1953, Aldous Huxley took four-tenths of a gram of mescaline, sat down and waited for the results. When he opened his eyes, he found everything, from the flowers in a vase to the creases in his trousers, was completely transformed.

With breathtaking immediacy he described this new 'sacramental vision of reality' in The Doors of Perception. In its sequel, Heaven and Hell, he went on to explore the history and nature of mysticism.

Two classic complete books -- The Doors of Perception (originally published in 1954) and Heaven and Hell (originally published in 1956) -- in which Aldous Huxley, author of the bestselling Brave New World, explores, as only he can, the mind's remote frontiers and the unmapped areas of human consciousness. Hugely influential, still bristling with a sense of excitement and discovery, these intense and illuminating writings remain the most fascinating accounts of the visionary experience ever written.
