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 *
