9.284

肇曰：既越三界，安得三界之垢？生曰：三垢已離，故不在三界也。以無三，為不在三矣。

[Seng]zhao says: Having already surpassed the three realms, how could he have the defilements of the three realms? [Dao]sheng says: The three defilements are already abandoned, hence he is not in the three realms. Through the absence of the three, he is not in the three [realms].
