"I believe that if people would learn to use LSD's vision-inducing capability more wisely, under suitable conditions, in medical practice and in conjunction with meditation, then in the future this problem child could become a wonderchild."

"In studying the literature connected with my work, I became aware of the great universal significance of visionary experience. It plays a dominant role, not only in mysticism and the history of religion, but also in the creative process in art, literature, and science. More recent investigations have shown that many persons also have visionary experiences in daily life, though most of us fail to recognize their meaning and value. Mystical experiences, like those that marked my childhood, are apparently far from rare."

"I see the true importance of LSD in the possibility of providing material aid to meditation aimed at the mystical experience of a deeper, comprehensive reality. Such a use accords entirely with the essence and working character of LSD as a sacred drug."

"Reality is inconceivable without an experiencing subject, without an ego. It is the product of the exterior world, of the sender and of a receiver, an ego in whose deepest self the emanations of the exterior world, registered by the antennae of the sense organs, become conscious. If one of the two is lacking, no reality happens, no radio music plays, the picture screen remains blank."

"LSD wanted to tell me something. ... It gave me an inner joy, an open mindedness, a gratefulness, open eyes and an internal sensitivity for the miracles of creation."
