The T'ang (618-907) and Sung (960-1279) dynasties were times of great change in China. The economy flourished, the population doubled, printing led to a great increase in the availability of books, Buddhism became a fully sinicized religion penetrating deeply into ordinary life. This volume represents a collaborative effort of nine scholars of Chinese religion, history, and thought to begin addressing the question of how changes in the religions of the Chinese people were implicated in the momentous social and cultural changes of this period.
