The basic principles of eastern philosophies have been practiced for at least 2,500 years. At the heart of all eastern philosophies is the belief expressed in the Chandogya Upanishad: "What that Unknowable is by which this universe subsists, that is the real, that is the soul, that art thou." In this study, best-selling author Blaize Clement explores the history, beliefs, and practices of Hinduism, Buddhism, Confucianism, and Taoism, with adaptations of the Mahabharata and the Ramayana.
