四分律行事鈔資持記 1.142

1.142

大段第三，示所詮行相，初總示中。宅，居也。佛門廣大，包納清澄，喻之如海；僧稟佛化，即居其中；如犯重禁，名為邊罪，謂漂出佛海邊外，即其義也。流即是水，法能滋物，故比於水。廁，預也。伍，眾也。此明比丘身具三寶，所修法行，雖乃萬途；以眾自共，攝無不盡。然據行體，止是二持；但就作中，別簡一色；羯磨僧法以為眾行；自餘雜法，總歸共行。欲使綱目兩分，眾別無濫，故云唯三位也。

In the third major section, indicating the marks of practice that are elucidated, first in the general indication: "Dwelling" (宅) means to reside. The Buddha's gate is vast, encompassing, receptive, and pure, compared to an ocean; the Saṃgha receives the Buddha's transformation and resides right within it. If one commits a grave prohibition, it is called a "marginal offense" (pārājika), meaning one is washed out beyond the margin of the Buddha-ocean—such is its meaning. "Current" means water; the Dharma can nourish things, so it is compared to water. "To participate" (廁) means to partake. "Ranks" (伍) means the assembly. This clarifies that the body of a bhikṣu is endowed with the Triratna; the Dharma-practices cultivated, though manifold, are completely subsumed under the community, personal, and shared [practices]. However, based on the essence of practice, there are only the two maintenances; but within positive action, a distinct category is singled out: karmavācanā and Saṃgha-dharmas are taken as community practice, while the remaining miscellaneous dharmas all return to shared practice. In order to divide the overarching outline from the specific details, leaving no confusion between the collective and the distinct, it says, "there are only three categories."
