大般涅槃經義記 6.52

6.52

下次超廣第三因緣，「復次，菩薩亦見亦知」總以標舉。下別顯之，行邪墮惡麁顯易了，觀矚分明故說為見；修善得脫微隱難識，觀照難明故不名見，說以為知。

Next, it skips ahead to extensively explain the third, causes and conditions: "Furthermore, the bodhisattva both sees and knows" summarizes and introduces it. Below, it distinguishes them: practicing evil and falling into wretched realms is coarse, apparent, and easy to understand; observing it clearly is therefore called seeing. Cultivating the good and attaining liberation is subtle, hidden, and difficult to recognize; contemplation and illumination being difficult to clarify, it is therefore not called seeing, but spoken of as knowing.
