In ''The Heart of the Buddha,'' the Tibetan meditation master Chogyam Trungpa presents the basic teachings of Buddhism as they relate to everyday life. The book is divided into three parts. In ''Personal Journey,'' the author discusses the open, inquisitive, and good-humored qualities of the ''heart of the Buddha,'' an ''enlightened gene'' that everyone possesses. In ''Stages on the Path,'' he presents the three vehicles--Hinayana, Mahayana, and Vajrayana--that carry the Buddhist practitioner toward enlightenment. In ''Working with Others,'' he describes the direct application of Buddhist teachings to topics as varied as relationships, drinking, children, and money. ''The Heart of the Buddha ''reflects Trungpa's great appreciation for Western culture and deep understanding of the Tibetan Buddhist tradition, which enabled him to teach Westerners in an effective, contemporary way.
