三彌勒經疏 1.63

1.63

經曰「爾時世尊出廣」以下，第二辨演法獲利。此中三：初現相、次說法、後得利。是初也。世尊者，即釋迦如來。出舌者，表授彌勒記，濟度有緣類不妄語也。放千光明者，表小千界各有化佛，破眾生暗故。各有千色者，表中千界各有千佛也。有無量佛者，表大千界當來時有百億彌勒一時生也。

From the sūtra's statement, 'At that time the World-Honoured One put forth his broad [and long tongue]...' onward is the second part: expounding the Dharma and obtaining benefits. Within this, there are three sections: first, manifesting signs; second, expounding the Dharma; third, obtaining benefits. This is the first. 'World-Honoured One' refers to Śākyamuni Tathāgata. Putting forth his tongue signifies that in bestowing the prophecy (vyākaraṇa) upon Maitreya and delivering all beings with affinities, he does not speak falsely. Emitting a thousand rays of light signifies that in each of the lesser thousand worlds there is an emanated Buddha dispelling the darkness of sentient beings. Each having a thousand colours signifies that in each of the medium thousand worlds there are a thousand Buddhas. Having immeasurable Buddhas signifies that when the future arrives in the great trichiliocosm, there will be ten billion Maitreyas born at the same time.
