相攝中，初文，前明僧村可攝餘界。藍中有村，則不相攝，二皆強故。樹舍者，舍即堂庫等。諸下，明餘界自不相攝。互相通涉，故無別勢分。

Under "Subsumption": regarding the initial text, it first explains that a saṅgha village may subsume other boundaries. If there is a village within the monastery grounds (ārāma), they do not subsume each other, because both are strong. "Trees and dwellings": "dwellings" refers to halls, storehouses, and the like. "Various..." below explains that other boundaries do not subsume each other among themselves. They mutually interpenetrate, so there is no separate force-field (śaktibhāga).
