注維摩詰經 4.237

4.237

無盡燈者，譬如一燈然百千燈，冥者皆明，明終不盡。如是諸姊！夫一菩薩開導百千眾生，令發阿耨多羅三藐三菩提心，於其道意亦不滅盡，隨所說法而自增益一切善法，是名無盡燈也。

As for the Inexhaustible Lamp: it is, for example, like a single lamp lighting hundreds of thousands of lamps; those that were dark all become bright, and its brightness is never exhausted. In this way, sisters, a single bodhisattva guides hundreds of thousands of sentient beings, causing them to generate the resolve for anuttarasamyaksaṃbodhi, and in their intention toward the Way there is also no extinction; in accord with whatever Dharma is expounded, they themselves increase all wholesome dharmas. This is named the Inexhaustible Lamp.
