(Chu) Tao-sheng stands out in history as a unique and preeminent thinker whose paradigmatic, original ideas paved the way for the advent of Chinese Buddhism. The universality of Buddha-nature, which Tao-sheng championed at the cost of excommunication, was to become a cornerstone of the Chinese Buddhist ideology. This book presents a comprehensive study of the only complete document by Tao-sheng still in existence.
