Aldous Huxley wrote his beautiful book The Doors of Perception after only one mescaline trip, and he took psychedelics only ten times during his life.* Similarly, when the great historian of religion Huston Smith published his collected reflections on psychedelics, Cleansing the Doors of Perception, he had taken LSD only a half dozen times. After that, he said, "The utility seemed to go down quickly and the bummers increased," leading him to adopt Alan Watts's advice: "When you get the message, hang up the phone." This book is about what happens if you don't hang up the phone.
