俱舍論疏 24.148

24.148

論「謂有學聖至成彼煩惱」，指事釋也。如有學聖先以無漏道離無所有處煩惱，後依四禪練根至解脫道，捨前鈍果及向，唯得四禪已下不還果道上三無色。若無先修有漏道得無為者，無漏得捨有漏得，無煩惱應成。既不成煩惱，明知有有漏得。

On the Śāstra's statement: "Namely, a noble learner up to possessing those afflictions": This points to a concrete case to explain it. For instance, a noble learner first abandons the afflictions of the sphere of nothingness by means of an anāsrava path; later, relying on the fourth dhyāna, they train their faculties (indriyasaṃskāra) up to the path of liberation, renouncing the previous dull fruit and path, and attaining only the path of the non-returner from the fourth dhyāna down and the three higher formless [absorptions]. If there were no prior cultivation of the āsrava path's possession of the unconditioned, when the anāsrava possession is renounced and there is no āsrava possession, the afflictions should be established. Since the afflictions are not established, it is clear that there is āsrava possession.
