Huayan Buddhism is regarded as one of the most philosophical schools of Chinese Buddhism, representing the elite-scholar Buddhism under the Tang Dynasty. Its vision of truth is based on the Avatamsaka Sutra, the scripture that Huayan masters studied, explained, and commented intensively throughout their lives. This was the common vocation of these monks, which gradually created a lineage of the Huayan tradition, a succession of exegetes who believed that the Avatamsaka Sutra was the consummate teaching of Buddha preached directly after (...) his enlightenment under the bodhi tree.
