The author of The Seven Storey Mountain explores the mysticism of Saint John of the Cross. The only thing that can save the world from complete moral collapse is a spiritual revolution. . . . The desire for unworldliness, detachment, and union with God is the most fundamental expression of this revolutionary spirit.   In Ascent to Truth, author and Trappist Monk Thomas Merton makes an impassioned case for the importance of contemplation. Drawing on a range of thinkers—from Carl Jung to Pope Pius XII—Merton defines the nature of contemplative experience and shows how the Christian mysticism of sixteenth-century Spanish Carmelite Saint John of the Cross offers essential answers to our disquieting and troubling times.   “For any who have the desire to look into meditation and contemplation . . . this is the book for which they have waited.” —New York Herald Tribune Book Review   “For those who may be curious about mysticism, and for those who may be called to a life of contemplation, this is an excellent book.” —Catholic World
