首楞嚴義疏注經 6.73

6.73

"If there are devas who delight in escaping their celestial species, I appear in the body of a deva and expound the Dharma for them, causing them to achieve [their wish]. If there are nāgas who delight in escaping their nāga species, I appear in the body of a nāga and expound the Dharma for them, causing them to achieve [their wish]. If there are yakṣas who delight in transcending their own species, I appear before them in the body of a yakṣa and expound the Dharma for them, causing them to achieve [their wish]. If there are gandharvas who delight in casting off their species, I appear before them in the body of a gandharva and expound the Dharma for them, causing them to achieve [their wish]."
