俱舍論記 5.19

5.19

「即如是類至豆等同分」者，此即第五經部答。相似種類諸行生時，於中假立人同分等，無別實體，如諸穀等同分非實。

As for "It is precisely when saṃskāras of such a class ... the generic conformity of beans and so forth": this is the fifth, [namely,] the Sautrāntika answering: "When conditioned phenomena of similar classes arise, one nominally posits human generic conformity and so forth among them without any separate real substance, just as the generic conformity of various grains and so forth is not real."
