Introduction to the remaining wall: Although the Huayan Sect was established mainly based on the Huayan Sutra of the Great Buddha, it also relied on Buddhist scriptures such as Prajna, Nirvana, Brahma Net, and Mahayana Awakening of Faith. The classics are also eclectic. They not only inherit the teachings of the masters of Di Lun and She Lun, but also critically absorb the relevant thoughts of Tiantai and Faxiang Sect. After harmonization and blending, they form a large and complete theoretical system of their own. This sect does not adhere to the original meaning of Buddhist scriptures and repeats them as written. Instead, it reorganizes them to form its own system, with a high degree of Chineseization.
