What is mysticism? The question continues to be the subject of fierce debate. Some argue that all mystical experience is the same - it is an innate human ability - while others insist that the nature of mystical experience is highly conditioned by the cultural and religious background of the mystic. There is, however, no disagreement about the identity of the mystics themselves. In this book, William Harmless offers a highly readable introduction to the mystics and their message. Their message, he says, centers on three topics: who God is, how we meet God in prayer; and why the human heart is at once so deep, so beautiful, so selfish, and so hard to fathom. By introducing students and general reders to these figures, he hopes to stimulate reflection on these great questions, and deeper exploration of the world's mystical traditions. In an era of growing interest in mysticism the need for introductions that are clear and accessible without sacrificing scholarly rigor and depth of understanding is great. Few books meet this exacting standard, but William Harmless's Mystics proves that the balance between outreach and analysis is not an impossible task. Harmless's Mystics, based on years of classroom experience in teaching mysticism, is a model for a concise and thoughtful approach to this intriguing, but difficult, topic. It will be necessary reading for all those who wish to explore the message of the mystics.
