備云：即據真如勝義諦故離言自性，世俗諦故假說自性，此之二境等無差別，即是二種無分別智所行境界。三藏亦同此解。

Bei says: In terms of tathatā as ultimate truth, it is the nature beyond words; in terms of conventional truth, it is the nature of metaphorical designation. These two realms are equally without distinction; they are precisely the objective sphere traversed by the two kinds of non-conceptual wisdom. The Tripiṭaka Master also concurred with this interpretation.
