61.101

疏「受恩常念小恩大報」者，即《涅槃》文，〈十行〉已引。「眾生於我有恩」者，若無眾生，不能成我普賢行故。

Regarding the commentary's 'Receiving kindness and constantly being mindful of repaying a small kindness with a great one,' this is a passage from the Nirvāṇa [Sūtra], already cited in the 'Ten Practices' [chapter]. 'Sentient beings have kindness toward me' means that without sentient beings, I could not accomplish the practices of Samantabhadra.
