首楞嚴義疏注經 6.79

6.79

「若諸眾生樂人修人，我現人身而為說法，令其成就。若諸非人有形無形、有想無想樂度其倫，我於彼前皆現其身而為說法，令其成就。」

"If there are living beings who delight in humans and cultivate human [conduct], I appear in the body of a human and expound the Dharma for them, causing them to achieve [their wish]. If there are non-humans—whether having form or formless, whether with thought or thoughtless—who delight in transcending their species, I appear before them all in their bodily forms and expound the Dharma for them, causing them to achieve [their wish]."
