天台四教儀 1.15

1.15

次明方等部，《淨名》等經，彈偏折小，歎大褒圓。四教俱說，藏為半字教，通、別、圓為滿字教。對半說滿，故言對教。若約時，則食時（第三時）；若約味，則從酪出生酥。此從九部出方等（三生酥味）。〈信解品〉云：「過是已後，心相體信，入出無難，然其所止猶在本處。」此領何義？答：三藏之後次說方等，已得道果，心相體信，聞罵不瞋。內懷慚愧，心漸淳淑。

Next, to clarify the Vaipulya division: In sūtras such as the Vimalakīrti, he censured the biased and reproved the small, while praising the great and extolling the perfect. All four teachings were preached together: the Tripiṭaka is the half-letter teaching, while the shared, distinct, and perfect are the full-letter teachings. Because the full is preached in contrast to the half, it is called the contrasting teaching. In terms of period, it is the mealtime (the third period); in terms of flavor, from curdled milk comes raw butter—here, from the nine divisions comes Vaipulya (the third, the raw butter flavor). The 'Belief and Understanding' chapter states: 'After this had passed, their minds gained mutual trust and understanding; entering and exiting without difficulty, yet his dwelling was still in the original place.' What meaning does this convey? The answer is: after the Tripiṭaka, he next preached Vaipulya; having already attained the fruits of the path, their minds gained mutual trust and understanding, so that hearing reproaches they felt no anger. Harboring shame within, their minds gradually grew mellow and refined.
