“In mysticism that love of truth which we saw as the beginning of all philosophy leaves the merely intellectual sphere, and takes on the assured aspect of a personal passion. Where the philosopher guesses and argues, the mystic lives and looks; and speaks, consequently, the disconcerting language of first-hand experience, not the neat dialectic of the schools. Hence whilst the Absolute of the metaphysicians remains a diagram —impersonal and unattainable—the Absolute of the mystics is lovable, attainable, alive.”

“Religion is nothing but institutionalized mysticism. The catch is, mysticism does not lend itself to institutionalization. The moment we attempt to organize mysticism, we destroy its essence. Religion, then, is mysticism in which the mystical has been killed. Or, at least diminished.”

“Theologians may quarrel, but the mystics of the world speak the same language.”

“The heart of creativity is an experience of the mystical union; the heart of the mystical union is an experience of creativity.”

“The renaissance of interest in Eastern spiritual philosophies, various mystical traditions, meditation, ancient and aboriginal wisdom, as well as the widespread psychedelic experimentation during the stormy 1960s, made it absolutely clear that a comprehensive and cross-culturally valid psychology had to include observations from such areas as mystical states; cosmic consciousness; psychedelic experiences; trance phenomena; creativity; and religious, artistic, and scientific inspiration.”

“This act of total surrender is not merely a fantastic intellectual and mystical gamble; it is something much more serious. It is an act of love for this unseen person, who, in the very gift of love by which we surrender ourselves to his reality also makes his presence known to us.”
