1.183

經曰「阿難當知」以下，第二會也。行事供養者，《大成佛經》云「行四事供養」，謂前施仁等也。

From the sūtra saying "Ānanda, you should know..." onward is the second assembly. Regarding "practicing offerings of actions," the Great Attainment of Buddhahood Sūtra says "practicing the four kinds of offerings," meaning the aforementioned generosity, benevolence, and so forth.
