俱舍論疏 21.156

21.156

論「此離俱繫至而不別說」，述自不立意也。雖五緣中離俱繫與滅雙因及越界緣，雖義有異，亦合別立。然說此俱因離時，即成俱繫離等。雖義有異，用無別故，而不別說。

The Śāstra says: "This release from conjoined bondage, down to: hence it is not separately stated." This explains the intention of not establishing it oneself. Although among the five conditions, release from conjoined bondage, extinguishing both causes, and the condition of transcending the realm are different in meaning and could appropriately be established separately, nevertheless, when one speaks of the release from both causes, release from conjoined bondage and so forth is accomplished immediately. Although they differ in meaning, because there is no difference in function, it is not separately stated.
