1.634

汝等雖住魔宮。以是無盡燈令無數天子天女發阿耨多羅三藐三菩提心者。為報佛恩亦大饒益一切眾生　三結勸學也。肇曰。報恩之上莫先弘道。

"Although you dwell in the māra's palace, by means of this inexhaustible lamp causing countless sons of devas and heavenly maidens to give rise to the mind of anuttarā-samyak-saṃbodhi, you will repay the Buddha's kindness and also greatly benefit all sentient beings." Third concludes by encouraging them to learn it. Zhao says: "Of the ways to repay kindness, none takes precedence over propagating the Way."
