四分律行事鈔資持記 3.358

3.358

檀越淨三種：初食是他物，處是己有。即施主寄食僧界，隨用施僧也。食具即所食之物。二處是他物，食具己有。如文自顯。三俱是者。即今俗舍設會供僧也。

The three types of dānapati-pure: first, the food is another's property, and the place is one's own possession. That is, a donor leaves food stored within the monastic boundary, offering it to the sangha according to need. 'Food utensils' are precisely the food items. Second, the place is another's property, and the food utensils are one's own possession. This is self-evident from the text. Third, both belong to the other. That is when today an assembly is hosted in a layperson's house to offer food to the sangha.
