佛說仁王般若波羅蜜經 1.32

1.32

佛告諸得道果實天眾：「善男子！是月光王已於過去十千劫中，龍光王佛法中，為四住開士，我為八住菩薩。今於我前大師子吼。如是，如是！如汝所言，得真義說，不可思議，不可度量，唯佛與佛，乃知斯事。

The Buddha addressed the assembly of devas who had attained the fruits of the path: "Good sons! In the past, during ten thousand kalpas in the Dharma of King of Dragon Light Buddha, this King Candraprabha was an opening knight of the fourth abode, while I was a bodhisattva of the eighth abode. Now, before me, he roars the great lion's roar. Thus it is! Thus it is! Just as you have spoken, you have attained the exposition of the true meaning, which is inconceivable and immeasurable. Only a buddha and a buddha can know this matter.
