1.83

經。當以飲食至比丘僧　三為修功文分為三。一教供養。二教禮懺。三教諷誦。此則初也。當以飲食供養比丘者。是供僧寶。

Sūtra: “One should with food and drink […] the bhikṣu-saṃgha.” / Third, cultivating merit. The text is divided into three parts: first, teaching making offerings; second, teaching worship and confession; third, teaching recitation. This is the first part. “One should with food and drink make offerings to the bhikṣus” means making offerings to the Jewel of the Saṃgha.
