3.286

詳曰：不可。若爾，扶塵應亦初句，有他用義，如田宅等。若言屬自非初句者，宅等應然，亦屬自故。若言扶塵屬自內身不相例者，祇由此義扶塵名為不共中共，宅等名為共中不共，外、內異故，復不屬他，故非初攝。

Deliberation: That cannot be. If so, the supporting physical matter should also be the first phrase, having the sense of being used by others, like fields and houses. If you say it belongs to oneself and is not the first phrase, houses and the like should be the same, as they also belong to oneself. If you say that the supporting physical matter belongs to one's own internal body and cannot be compared, it is precisely because of this meaning that the supporting physical matter is called the shared within the unshared, while houses and the like are called the unshared within the shared. Because external and internal differ, and moreover they do not belong to others, they are not subsumed under the first.
