俱舍論記 5.237

5.237

「此名身等至此皆應辨」者，此下大文第三諸門分別。就中，一辨名等三、二辨同分等。此即第一辨名等三，總有四門：一問繫界；二問情、非情；三問五類；四問三性。以實唯無為，剎那唯苦忍，故於五類不別標問。

Regarding the passage 'These collections of names, etc. ... all these should be distinguished': below this is the third major section, distinction through various categories. Within this: first, distinguishing the three [factors] of name and so forth; second, distinguishing nikāya-sabhāga and so forth. This is the first, distinguishing the three of name and so forth, which has four categories in total: first, inquiring about the realm of attachment (dhātu); second, inquiring about the sentient and the non-sentient; third, inquiring about the five classes; fourth, inquiring about the three natures. Because in reality it is only unconditioned, and the momentary is only the forbearance of suffering, the five classes are not specifically labeled and asked about.
