問。後漢書云。佛道神化興自身毒（案山海經。西方有天毒國。郭景純注云。即天竺國也。而漢書西域傳云。天竺國一名身毒國也）詳其清心釋累之訓。空有兼遣之宗。道書之流也。以此推之。則道教收佛。又佛經云。一切文字。悉是佛說。非外道書。而先生高位釋教。在儒道之表。將不自局而近誣聖乎。

Question: The Book of the Later Han states that the miraculous transformations of the Buddha's Way arose from Shendu. (According to the Shanhai jing, in the west there is the kingdom of Tiandu. Guo Jingchun's commentary states that it is the kingdom of Tianzhu. And the 'Account of the Western Regions' in the Book of the Han states that Tianzhu Kingdom is also called Shendu Kingdom.) Examining its teachings on purifying the mind and releasing entanglements, and its principle of simultaneously casting off emptiness and existence, it is of the same stream as Daoist texts. Deducing from this, Daoist teaching subsumes the Buddha. Furthermore, Buddhist sūtras state that all written words are spoken by the Buddha and are not texts of external paths. Yet you, sir, elevate the Buddhist teaching above Confucianism and Daoism; are you not limiting yourself and thereby coming close to slandering the sage?
