四分律刪繁補闕行事鈔 2.212

2.212

初明僧次七緣：一有施主；二是僧次請；三五正食，在時中；四食處成眾；五知界內有善比丘未食，不集；六無諸緣；七咽咽犯。《多論》：若施主就僧界內二處設食，應布薩處請僧，或送一分食，自處不須展轉。若聚落界內無僧界，二施主各請四人已上，二處食，應打楗稚，互請一人，互送一分食；更有異比丘入，亦更須展轉。或先僧次後成別請，有客遮不許入是；若不遮，雖先別請，後成僧次。如上立法，此明僧次。

First, explaining the seven conditions for monastic rotation: first, there is a donor; second, it is an invitation by monastic rotation; third, it involves the five staple foods and is at the proper time; fourth, a quorum is formed at the eating place; fifth, knowing that there are good bhikṣus within the boundary who have not eaten, one fails to assemble them; sixth, there are no valid reasons; seventh, an offense is incurred with every swallow. The Sarvāstivāda-vinaya-vibhāṣā states: 'If a donor provides food in two places within the monastic boundary, one should invite the saṃgha at the upoṣadha hall, or send one portion of food; one's own place need not involve succession. If within the village boundary there is no monastic boundary, and two donors each invite four or more persons to eat in two places, the gaṇḍī should be struck, one person should be mutually invited, and one portion of food mutually sent; if another different bhikṣu enters, succession must also be observed again. Or, what was initially a monastic rotation later becomes an individual invitation, as when there are visiting monks who are obstructed and not permitted to enter; if not obstructed, though initially an individual invitation, it later becomes a monastic rotation.' The rule established as above explains monastic rotation.
