俱舍論記 17.6

17.6

「故於此中至俱極成故」者，此顯名同，攝諸異類。故於此釋業道名中，言業道者具顯後三業道，前七業、業道義。若言業道，業是貪相應思，道是思相應貪等。若言業業道，上業是身、語，下業是因等起思，道是身、語。此中意說：一業顯多業、一道顯多道。雖復業、道性類不同，業名同故，而一業名為餘業故；道名同故，而一道名為餘道故。如斯之類於世間中、於典籍中俱極成故。世極成者，如言車牛，雖多車牛性類不同，車牛名同，而一車牛名為餘車牛故。典極成者，如言識住，雖四識住性類不同，識住名同，而一識住名為餘識住故。

Regarding "Therefore herein [...] because both are well established": this shows that the name is identical while subsuming different categories. Therefore, herein, in explaining the designation 'path of karma', the phrase 'path of karma' fully reveals the meaning of 'path of karma' for the latter three, and 'karma and path of karma' for the former seven. If one says 'path of karma', karma is volition associated with covetousness, and the path is covetousness and so forth associated with volition. If one says 'karma and path of karma', the former karma is bodily and verbal, the latter karma is volition as the causal originator, and the path is bodily and verbal. What is meant here is: one 'karma' reveals multiple karmas; one 'path' reveals multiple paths. Although the natures and categories of karma and path are different, because the name 'karma' is identical, one name 'karma' stands for the remaining karmas; because the name 'path' is identical, one name 'path' stands for the remaining paths. Things of this kind are well established both in the world and in standard treatises. 'Well established in the world' is like saying 'cart and ox': although multiple carts and oxen differ in nature and category, because the name 'cart and ox' is identical, one 'cart and ox' stands for the remaining carts and oxen. 'Well established in treatises' is like saying 'station of consciousness': although the four stations of consciousness differ in nature and category, because the name 'station of consciousness' is identical, one 'station of consciousness' stands for the remaining stations of consciousness.
