仁王般若經疏 3.62

3.62

所言月光者，性月，名波斯匿。而言月光者，當是受法已後更立光字，故云月光也。次發言者，見釋迦神力，復見寶滿如來化身佛主，復見千葉上佛各各說般若，此三處佛為一為異？

Regarding "Candraprabha": his family name was Moon (Candra), and his personal name was Prasenajit. As for calling him "Candraprabha" (Moonlight), it must be that after receiving the Dharma the character "prabha" (light) was added to his name; hence he is called Candraprabha. Next, regarding his utterance: he saw Śākyamuni's supernatural power, further saw Ratnapūrṇa Tathāgata as the master of the transformation-body buddhas, and further saw the buddhas upon the thousand petals each preaching prajñā—are the buddhas in these three places one or different?
