大方便佛報恩經 2.52

2.52

爾時會中有一大菩薩摩訶薩，名曰喜王，即從座起，偏袒右肩，右膝著地，合掌仰白如來，而作是言：「菩薩云何知恩報恩？」

At that time in the assembly there was a great bodhisattva-mahāsattva named Prītirāja, who arose from his seat, bared his right shoulder, knelt with his right knee on the ground, joined his palms, and looking up addressed the Tathāgata, saying: "How does a bodhisattva know kindness and repay kindness?"
