弘明集 6.39

6.39

通源曰。殊時故不同其風。異世故不一其義。吾見道士與道人戰儒墨道人與道士獄是非。昔有鴻飛天首積遠難鳧。越人以為鳧。楚人以為乙。人自楚越耳。鴻常一鴻乎。夫澄本雖一吾自俱宗其本鴻跡既分。吾已翔其所集。

Penetrating the Source says: Because their times were different, their customs were not the same; because their ages were diverse, their significance was not identical. I see Daoists battling with śramaṇas, and Confucians, Mohists, and śramaṇas holding trials of right and wrong with Daoists. Once, a wild goose flew across the expanse of the sky; because of its great distance, it was hard to tell from a duck. A person of Yue took it for a duck, and a person of Chu took it for a swallow. The people were merely of Chu and Yue—was the wild goose ever anything other than one wild goose? Although the pure root is one, I naturally revere both; as its root has poured forth and its traces have divided, I have already soared to where it settles.
