御注金剛般若波羅蜜經宣演 2.229

2.229

經。若有善男子至其福勝彼　演曰。正校量。論云。以有如是大利益故。決定應演說。如是演說而無所染。彼論云。雖諸佛自然化身作業。而彼諸佛化身說法。有無量無盡無漏功德故。

Sūtra: If a good man, up to: his merit surpasses that. Exposition: Directly weighing [the merits]. The treatise says: 'Because there is such great benefit, one definitely ought to explain it; thus explaining it, one is without defilement.' That treatise says: 'Although all Buddhas spontaneously perform deeds through nirmāṇakāyas, when those nirmāṇakāyas of the Buddhas teach the Dharma, they possess immeasurable, endless, and uncontaminated merits.'
