The Varieties of Psychedelic Experience: The Classic Guide to the Effects of LSD on the Human Psyche
"A wonderful book . . . the best book ever written in this complicated field." (Dr. Timothy Leary)"Beautifully written . . . Masters and Houston are offering what amounts to a whole new system of psychopathology." (New York Times Book Review)"Fascinating . . . provocative . . . The first description of the multiplicity of experiences available through these drugs presented in a manner oriented to western culture and experimental research." (Library Journal)"The most brilliant volume available dealing with the psychedelic experience." (Dr. Stanley Krippner)"I consider the book very important and worthwhile. It is all in the right direction; it gives very sound directives for controlling the use of psychedelics instead of merely repressing them." (Alan Watts)
