大般涅槃經集解 32.42

32.42

案道生曰：有多惑故為世諦，無多解故為第一義也。僧亮曰：上說苦是第一義，今說為世諦也。僧宗曰：第五重明金剛以還未免苦為世諦。唯佛果對八苦相，故名第一義也。寶亮曰：釋同。

Daosheng notes: "Because there are many delusions, it is the conventional truth; because there are not many understandings, it is the ultimate truth." Sengliang says: "Above, suffering was said to be the ultimate truth; now it is said to be the conventional truth." Sengzong says: "The fifth layer clarifies that prior to the diamond [-like samādhi], one is not yet free of suffering, which is the conventional truth. Only the Buddha fruit is contrasted with the marks of the eight sufferings, and is therefore called the ultimate truth." Baoliang says: "The explanation is identical."
