1.377

以一食施一切。供養諸佛及眾賢聖然。後可食　此明悲施。肇曰。因誨以無礙施法也。若能等邪正。又能以一食等心施一切。然後自食。若得法身則能實充足一切。如後一鉢飯也。

"Giving one portion of food to all, making offerings to the buddhas and the assembly of worthy ones and sages, and only then may you eat." This explains compassionate giving. Sengzhao says: "Because of this, he instructs him in the dharma of unhindered giving. If one can equalize the heterodox and the correct, and can also with an equal mind give one portion of food to all, and only then eat oneself—if one attains the dharmakāya, then one can truly satisfy all, just like the single bowl of rice later on."
