俱舍論記 16.29

16.29

「論曰至別有體故」者，釋上三句。貪、瞋、邪見亦名惡行，離思別有，故復開三。離身、語業更無別體，故於身、語不可說也。或此三種，惡行相應故名惡行。

Regarding "The treatise says: ... having distinct essences": This explains the upper three lines. Greed, malice, and wrong view are also called evil conduct; because they exist distinct from cetanā, three more are opened up. Since they have no distinct essence apart from bodily and vocal karma, they cannot be spoken of with respect to body and speech. Alternatively, these three are called evil conduct because they are associated with evil conduct.
