大般涅槃經義記 6.289

6.289

就前番中，初先辨定三字之義，所言為者為於佛性，為令眾生見於佛性是以言為；言阿闍者，此名不生；世是梵語，此翻名怨。次約人論，人有迷悟。若就迷者，將不生義與性相屬，迷惑之人不生性故；若就悟者，牽不生義與怨相屬，悟解之人不生怨故。

In the former round, he first determines the meaning of the three words: that which is called "for" (wei) means for the sake of the buddha-nature; because it causes beings to see the buddha-nature, it is said to be "for." What is called "Ajāta" means "unborn." "Śatru" is a Sanskrit word, translated here as "enemy." Next, discussing in terms of persons, people have delusion and awakening: if in terms of the deluded, the meaning of "unborn" is connected to nature, because deluded persons do not give rise to the [manifestation of] nature; if in terms of the awakened, the meaning of "unborn" is linked to enemy, because awakened persons do not give rise to enemies [of afflictions].
