仁王般若經疏 1.84

1.84

時波斯匿王下，說經時序中第六明月光及諸天等作樂歎佛，召集十方眾來聞經。就中有三：初月光作八萬種音樂；二十八梵下，諸天作樂歎佛；三彼他方下，明十方菩薩雲集，作無量音樂覺悟如來。南方法戈菩薩者，各以一德彰其號也。入二禪尚無，為聲判所動。今言覺悟如來者，此明有機感佛耳。

From "Then King Prasenajit" downward is the sixth [part] within the introductory section of the time of expounding the sūtra, clarifying that Moonlight, the devas, and others made music to praise the Buddha, summoning and gathering the assemblies of the ten directions to come and hear the sūtra. Therein are three [parts]: first, Moonlight produces eighty thousand kinds of music; from "the twenty-eight Brahmā" downward, the devas produce music to praise the Buddha; third, from "in those [Buddha-lands] of other directions" downward, clarifying that bodhisattvas of the ten directions gathered like clouds, producing immeasurable music to awaken the Tathāgata. As for the bodhisattva Dharmaketu of the south, each is distinguished in name by a single virtue. One who enters the second dhyāna is not even moved by sounds. Now saying "to awaken the Tathāgata" clarifies that there was a capacity that resonated with the Buddha.
