The philosophy of Buddhism, originating in India, has undergone considerable changes in its adoption in the Far East. It has, in Japan, assumed a more practical aspect, and has come to play an important role in the everyday life of action. But in this process Japanese Buddhism has split itself into many sects with greatly differing doctrines, though all profess a method destined to elevate the soul and a method of action. The understanding of this spiritual movement is an important key to the understanding of the contemporary Japanese state of mind, and The Buddhist Sects of Japan gives the first complete account of it in the English language.
