Campbell uses stories of the Buddha's life and enlightenment to reflect the essence of the Buddhist religion. He explains the difference between the two principal types of Buddhism - Theravada (Hinayana) and Mahayana. Campbell also probes the differences between Eastern and Western religion by focusing on Buddhism as a religion of "identification with" the divine rather than on of "relationship to" it. He also compares Buddhism with Taoism and Confucianism and explores an ancient collision of East and West.
