俱舍論疏 19.20

19.20

論「頌說亦言至義如後辨」，別釋頌中置「亦」意也。如衣有潤，塵埃隨著。貪潤於境，嗔亦隨增。非唯於嗔，慢等亦爾，故言「亦慢」。

Regarding the treatise from "The word 'also' in the verse... up to... the meaning will be analyzed later", this separately explains the intention behind placing the word 'also' (api) in the verse. Just as when clothing is moist, dust sticks to it; greed moistens objects, and anger also increases accordingly. Not only with anger, but pride and the rest are also like this; hence it says "also pride".
