Huston Smith's masterpiece explores the essential elements and teachings of the world's predominant faiths, including Hinduism, Buddhism, Confucianism, Taoism, Judaism, Christianity, Islam, and the native traditions of Australia, Africa, Oceania, and the Americas. Emphasizing the inner--rather than the institutional--dimension of these religions, Smith devotes special attention to Zen and Tibetan Buddhism, Sufism, and the teachings of Jesus. He convincingly conveys the unique appeal and gifts of each of the traditions and reveals their hold on the human heart and imagination.
The Judaism chapter reads like a mathematical proof in places, and there are too many modern scientific parrallels in the Christianity chapter.
Aside from that a Very good book.
Smith's treatment of indigenous, animistic, pagan, and traditional practices were less complete than I had hoped to find.
