四分律行事鈔資持記 1.234

1.234

次明自然，初科分二，初示相。四中，聚蘭各二，則為六相。皆下，釋名。對彼作法，緣搆成故。當下，標所出。問：所以當律都不立者？答：止是闕略，義必具之。準三小界，明指集處；疏云雖當部中無自然界，異處下道，即是誠文；道是一界，下是蘭若。今言無者，或非明文，或無分齊故也。

Next, explaining the natural [boundaries]: the first heading is divided into two. First, it shows the marks. Among the four, village and araṇya each have two, making six marks. Beginning with "all" (皆), it explains the name: in contrast to those established through ritual-action, they are formed through conditions. Beginning with "this" (當), it indicates what they derive from. Question: Why is it that our own vinaya does not establish them at all? Answer: It is merely an omission; in meaning it must possess them. In accordance with the three small boundaries, it clearly indicates the gathering place. The Commentary states: although in our own school there is no natural boundary, descending from the road in a different place is authentic text; the road is one boundary, and descending from it is the araṇya. Saying here that it does not exist is either because there is no explicit text, or because there is no delimitation.
