When Buddhism (see Buddhism) first came to China in the first century bce it came in the many forms that had emerged in India and was brought by people who knew little Chinese and absorbed by people who knew little Sanskrit (see Sanskrit). In addition to this problem there was opposition from both the Confucian (see Confucianism) and Daoist (see Daoism) schools of religious and philosophical thought. It was not until the late fifth and early sixth centuries ce that Buddhism of a Mahāyāna (see Mahāyāna Buddhism) sort was able to weave itself fully into the fabric of Chinese life. By then it had become a spiritual complement to secular Confucianism and had provided the idea of Enlightenment to Daoism. In time, the three schools of thought would be seen as a complementary unity.
