3.442

三中。所授，即過食者。初科。五義者，指上《多論》。由有五義，故須餘眾，不許自類。六眾，道四俗二也。三趣，更兼非畜也。口受二局，眾局比丘，趣唯人道。

Within the third [heading], "the one who offers" refers to the person who hands over the food. The first heading: "five meanings" points to the Sarvāstivāda Vinaya Vibhāṣā above. Because there are five meanings, one must use another assembly, and is not permitted to use one's own kind. The six assemblies are the four monastic and two lay. The three destinies additionally include non-humans and animals. The two restrictions of reception by mouth are: the assembly is restricted to bhikṣus, and the destiny is only the human realm.
