大般涅槃經集解 20.56

20.56

案僧亮曰：眾生有心，知苦可厭、知樂可求。不識苦故，名無明也；識則無明之名轉也。是則有明闇之異不一也。

Sengliang states: Sentient beings possess a mind and know that suffering is to be detested and bliss is to be sought. Not recognizing suffering is called ignorance; when one recognizes it, the designation of ignorance is overturned. Thus there is the difference between illumination and darkness, and they are not identical.
