Thomas Merton was the most popular proponent of the Christian contemplative tradition in the twentieth century. Now, for the first time, some of his most lyrical and prayerful writings have been arranged into A Book of Hours, a rich resource for daily prayer and contemplation that imitates the increasingly popular ancient monastic practice of "praying the hours". Editor Kathleen Deignan mined Merton's voluminous writings, arranging prayers for Dawn, Day, Dusk, and Dark for each of the days of the week. A Book of Hours allows for a slice of monastic contemplation in the midst of hectic modern life, with psalms, prayers, readings, and reflections.
