大般涅槃經義記 3.71

3.71

第三段中，「其王得」者，邊地化主自聞經法即便分張；「舉國食」者，勸他同習；「民既食」下所化之人荷恩喜讚；順教奉修名為食已，慶沾法利所以皆喜；領荷四依弘化之恩，是故咸言「因彼王故得希有食」。

In the third passage, "when that king obtained it" means that when the master of conversion in the borderland himself heard the scriptural Dharma, he immediately distributed it; "the whole country ate it" means encouraging others to practice it together; from "after the people had eaten" onward, the converted people feel gratitude and praise it with joy; practicing in compliance with the teaching is called having eaten it; rejoicing in being touched by the benefit of the Dharma is why all were joyful; receiving and feeling gratitude for the kindness of the four refuges in propagating conversion is therefore why all said, "Because of that king, we obtained rare food."
