俱舍論疏 3.162

3.162

論「分別根中至何沙門果」，下一頌第三明得果用根多少。此中明得，通無間道、解脫道。與得果前為引因，後轉為依因。由此前後二果，定用二無漏根得也。此中言得，初證名得，不說後位及練根也。若說練根，初後二果應八根得。又此中言得，是與果道為其近因名之為得。

The treatise says: "Among the analyzed faculties, [which are used to attain] which śrāmaṇyaphala?" The next single verse is the third [section], clarifying how many faculties are used in attaining the fruits. Here, "attaining" covers both the uninterrupted path (ānantaryamārga) and the path of liberation (vimuktimārga). With respect to the attainment of the fruit, [the former] acts as an antecedent cause beforehand, while the latter subsequently transforms into a supporting cause. Because of this, the first and last of the two fruits are definitely attained by means of two anāsrava faculties. The word "attain" here refers to the initial realization, not to subsequent stages or the refining of faculties (indriyasaṃskāra). If one spoke of refining faculties, the first and last fruits would be attained by eight faculties. Furthermore, "attain" here means that being the proximate cause for the path of the fruit is called "attaining."
