佛祖統紀 47.43

47.43

The commentary says: The Confucian use of Laozi's and Zhuangzi's words has been practiced for a long time, so it cannot be eliminated overnight. As for the subtlety of exhausting principle and the profundity of penetrating human nature, rising high above the world and containing all things, nothing surpasses the books of the Buddha. However, if Confucians wish to clarify principle between Heaven and man, seeking it in the Book of Changes, the Great Plan, the Doctrine of the Mean, the Great Learning, the Analects, and Mencius is sufficient unto itself. If they stray into the words and ideas of the Buddhist sūtras, they contradict their own tradition and become unconstrained, having nowhere to return. How great was the admonition of Emperor Xiaozong! Did it not have profound purpose?
