大乘義章 2.85

2.85

第三門中辨其通局。世界悉檀，通其為人及與對治，而不通於第一義諦。即說世界差別法門，以為對治及為人，故世界悉檀通彼二中；不說世界為第一義，是故世界不通第一。非謂處別說為不通，淺深異故名不通耳。第一義者，分得通彼各各為人及對治中，不通世界，良以宣說第一義諦治物心患，是故第一通於對治。即就第一彰其為人各各不同，或說為有、或說為無、或復說為非有非無，或說為我、或說無我、或復宣說非我無我。如是種種為人差別，是故第一通彼各各為人悉檀。深淺別故，不通世界。對治、為人二種相望，一向相通，無別法故。

In the third section, their applicability and restriction are distinguished. The worldly siddhānta applies to the for-persons and the therapeutic, but does not apply to the ultimate truth. That is, preaching the differentiated approaches of the world serves as the therapeutic and for-persons; hence the worldly siddhānta applies to those two. The world is not spoken of as the ultimate; therefore the worldly does not apply to the ultimate. This does not mean that it is said to not apply because of different locations; it is called not applying because of the difference between shallowness and depth. The ultimate partly applies to the individual person and the therapeutic, but does not apply to the worldly. Precisely because preaching the ultimate truth cures the mental sicknesses of beings, the ultimate applies to the therapeutic. Pointing out that persons are distinct directly within the ultimate, it is sometimes spoken of as existent, sometimes as non-existent, or again as neither existent nor non-existent; or it is spoken of as self, sometimes as non-self, or again as neither self nor non-self. Such various differences for persons are why the ultimate applies to the individual person siddhānta. Because of the difference between depth and shallowness, it does not apply to the worldly. As for the two, the therapeutic and for-persons, when compared to each other, they are universally mutually applicable, because there is no separate dharma between them.
