俱舍論記 5.166

5.166

「然經重說至表善非善」者，經部釋經。然前經文說有三有為之有為相，經應但言有三有為之相。然經重說後有為言者，令知此能相表所相法體是有為。若但言有為之相，即不知此相定表所相法體是有為，或疑此相表有為是有，及善、惡等。故著後有為言，令知此相表所相法定是有為，故言勿謂此相表有為法是有。如白鷺所居表水非無，亦勿謂此相表有為法是善、惡。如童女相能表男、女善非善事。若性貞潔脚膝纖團、皮膚細軟齒白脣薄，必生善子。此相表善。若性不貞潔脚膝笨大、皮膚麁澁齒黑脣厚，生不善子。此相表非善。此有為相，不同白鷺表有水，不同童女相表善非善，但表所相法體是有為。

Regarding "Yet the scripture reiterates ... indicates good or non-good": the Sautrāntika explains the scripture. Although the preceding scriptural passage said there are three conditioned characteristics of the conditioned, the scripture should have simply said there are three characteristics of the conditioned. However, that the scripture reiterated the subsequent word 'conditioned' is to make it known that this characterizing mark indicates that the entity of the characterized dharma is conditioned. If it only said 'characteristics of the conditioned,' then one would not know that this characteristic definitely indicates that the entity of the characterized dharma is conditioned, or one might doubt that this characteristic indicates that the conditioned exists, or is good, bad, and so forth. Therefore, by adding the subsequent word 'conditioned,' it makes it known that this characteristic indicates that the characterized dharma is definitely conditioned; hence it says: do not think that this characteristic indicates that conditioned dharmas exist, just as the dwelling of a white heron indicates that water is not absent; nor should one think that this characteristic indicates that conditioned dharmas are good or bad, just as the physical marks of a maiden can indicate good or non-good events for men and women. If she is chaste, her legs and knees will be slender and rounded, her skin soft and smooth, her teeth white, and her lips thin, and she will certainly bear good sons; these marks indicate good. If she is not chaste, her legs and knees will be clumsy and large, her skin coarse and rough, her teeth black, and her lips thick, and she will bear bad sons; these marks indicate non-good. These conditioned characteristics are not like a white heron indicating the presence of water, nor like the marks of a maiden indicating good or non-good; they only indicate that the entity of the characterized dharma is conditioned.
