Tendai

Tendai (天台宗, Tendai-shū?) is a Japanese school of Mahayana Buddhism, a descendant of the Chinese Tiantai or Lotus Sutra school.

Chappell (1987: p. 247) frames the relevance of Tendai for a universal Buddhism:

Although Tendai (Chin., T'ien-t'ai) has the reputation of being a major denomination in Japanese history, and the most comprehensive and diversified school of Chinese Buddhism, it is almost unknown in the West. This meagre presence is in marked contrast to the vision of the founder of the movement in China, T'ien-t'ai Chih-i (538-597), who provided a religious framework which seemed suited to adapt to other cultures, to evolve new practices, and to universalize Buddhism.
