From Thomas Merton's legacy of spiritual writings comes A Book of Hours, a manual of mysticism, a set of teachings for engaged contemplatives, a guide for the formation of conscience, and a collection of koans, mantras, and prayers. With prayers for Dawn, Day, Dusk, and Dark for each day of the week, A Book of Hours brings the ancient monastic practice of praying the hours into our hectic modern lives, making hte ancient new, and the timeless timely.
