俱舍論疏 21.138

21.138

論「諸忍皆是至同一果故」，答也。有二義：一以忍是智眷屬故假名為智；二以智、忍同一果故。同一果者，有兩釋：一無間、解脫同一果故；二忍所得者至不還、阿羅漢果，亦為智果故。應依後釋。《正理》、《婆沙》皆同有此釋。

The treatise says: "All receptivities are […] because they have the same fruit": this is the answer. There are two meanings: first, because receptivity is the retinue of knowledge, it is metaphorically named knowledge; second, because knowledge and receptivity have the same fruit. Having the same fruit has two explanations: first, because the uninterrupted and liberation [paths] have the same fruit; second, because what is attained by receptivity, up to the fruits of non-returner and arhat, also becomes the fruit of knowledge. One should follow the latter explanation. Both the Nyāyānusāra and the Vibhāṣā identically contain this explanation.
