大般涅槃經集解 7.130

7.130

案道生曰：本不在字，則非字矣。耶說不在常，非常說也。僧亮曰：虫不識字，雖字非字，智者豈有識字之怪耶？不別諸病，悉用乳藥者，病起於麻麥之我，不可用我而為治。若起八自在之上者，可得用我治彼不識也。僧宗曰：上三脩中廣明八倒，但有其名未得其實，何異虫跡耶？

Daosheng comments: "Since the original intent was not to make characters, it is not writing at all. Heretical teachings do not intend permanence, so they are not teachings of permanence." Sengliang comments: "An insect does not know writing. Although there are characters, they are not true characters; how could a wise person find it astonishing as if it knew how to write? As for not distinguishing among various illnesses and prescribing milk medicine for all of them: if an illness arises from the 'self' of hemp and wheat, one must not use the 'self' to treat it. If it arises above the eight sovereign masteries, one may use the 'self' to treat their ignorance." Sengzong comments: "In the three cultivations above, the eight inversions were explained at length; having only the names without grasping their reality, how does that differ from the traces left by an insect?"
