注大乘入楞伽經 5.243

5.243

諸惑習種隨諸有情眠伏藏識故，謂隨眠為怨。明羅漢，習使微細不現，如鼠噬人，雖復瘡愈，遇雷微發。以譬羅漢習使雖復不現，遇緣微發。究竟斷此微細習使，名殺阿羅漢。

The latent seeds of all afflictions follow sentient beings, lying dormant in the storehouse consciousness; therefore the dormant afflictions are called enemies. Clarifying the arhat: subtle active predispositions do not manifest, just as when a rat bites a person, though the wound heals, it flares up slightly upon encountering thunder. This serves as an analogy that although the arhat's predispositions do not manifest, they flare up slightly upon encountering conditions. Utterly severing these subtle predispositions is called killing an arhat.
