俱舍論疏 26.43

26.43

論「三行相故至體無別故」，第三建立苦、集智也。此由苦、集體一用分，不由境別，但以行相不同，分其二智。

On the Śāstra's statement: "Third, because of aspects [...] because their entities are not distinct": third is establishing the knowledges of suffering and origination. Because suffering and origination are one in entity but divided in function, they are not divided on account of a difference in objective realm; they are divided into two knowledges solely on account of their aspects being different.
