Book excerpt: Buddhist teacher and anthropologist Joan Halifax delves into "the fruitful darkness" -- the shadow side of being, found in the root truths of Native religions, the fecundity of nature, and the stillness of meditation. In The Fruitful Darkness, a highly personal and insightful odyssey of the heart and mind, she encounters Tibetan Buddhist mediators, Mexican shamans, and Native American elders, among others. In rapt prose, she recounts her explorations -- from Japanese Zen meditation to hallucinogenic plants, from the Dogon people of Mali to the Mayan rain forest. Grove Press is proud to reissue this important work by one of Buddhism's leading contemporary teachers.
