觀音玄義 2.32

2.32

七方便普者，進行方便是道前方便，起用方便是道後方便。今正明道，後方便也。若二乘及小菩薩所行方便入一法門，若欲化他，齊其所得，起用化物，道前、道後俱非是普；圓教菩薩二諦為方便，收得一切方便，入中道已，雙照二諦，二諦神變遍十法界，而於法身無所損減，道前、道後皆名為普。

Seventh, universal upāya: upāya that advances practice is the upāya prior to the path; upāya that gives rise to function is the upāya subsequent to the path. Here we are specifically explaining upāya subsequent to the path. If the upāya practiced by the two vehicles and lesser bodhisattvas enters one dharma-gate, and when wishing to transform others, they give rise to function to transform beings only up to the level of their own attainment, then both before and after the path are not universal. Bodhisattvas of the perfect teaching take the two truths as upāya, subsuming all upāyas; having entered the middle way, they illuminate both truths, and the spiritual transformations of the two truths pervade the ten dharma-realms without diminishing the dharma-kāya in any way. Both before and after the path are called universal.
