成唯識論演祕 3.288

3.288

傳有二釋：一云：有漏不淨由同處故，業復少同，受用有別，名第二句。佛唯無漏，菩薩極淨，雖穢同處，淨、不淨業有差別故，非第二句。二云：淨穢其處既同，即是第二共中不共。

There are traditionally two explanations: One says: Sāsrava impurity, because of being in the same place and having slightly similar karma, yet having different enjoyment, is called the second phrase. A Buddha is exclusively anāsrava, and a bodhisattva is exceedingly pure; although they share the same place with the defiled, because pure and impure karma have distinctions, they are not the second phrase. The second says: Since the pure and the defiled share the same place, it is precisely the second: the unshared within the shared.
