華嚴經探玄記 7.15

7.15

First, explaining the title: this clarifies that as the Tathāgata is about to preach the wondrous Dharma, eminent disciples will surely rush like shadows, arriving swift as lightning and gathering like clouds, filling space and assembling in the dharmadhātu, each praising the Buddha's true virtues with wondrous verses; hence it is named after this. Furthermore, 'heavenly palace' is the place; 'bodhisattvas' indicates the persons; 'gathering like clouds' is mastery of bodily karma; 'praising the Buddha' is the merit of vocal karma. The title is given according to body, speech, place, and function.
