宗密=Zongmi; 《起信論》=Dasheng qixin lun(Awakening of Faith in the Mahāyāna); 《圓覺經大疏》=Yuanjue jing dashu (Full Commentary on the Yuanjue jing); 真心本體論=True Mind Ontology; 會通思維= integrative thinking
Although Zongmi is known as the fifth patriarch of the Huayan School, he replaced the Huayan jing (mahā-vaipulya-buddhâvataṃsaka-sūtra) with the Yuanjue jing (The Sutra of Complete Enlightenment) and used the Dasheng qixin lun (Awakening of Faith in the Mahāyāna) to interpret it, changing the tradition of the Huayan School into a kind of true mind ontology. This amounted to a paradigm shift in the interpretation of Chinese Buddhism. It pushed the Huayan School towards the Chan school so much that it even became a footnote of the latter. Thus, the Yuanjue jing, a sutra of dubious origin, influenced the thought of Zongmi, and through the canonical position it attained through Zongmi's interpretations it itself would play an influential role in the integration of Confucianism, Daoism and Buddhism.
