仁王般若經疏 3.51

3.51

佛告大王：「如是如是。如王所說般若波羅蜜，應說應受，是諸佛母、諸菩薩母，神通生處。」

The Buddha told the great kings: "So it is, so it is! As the kings have said, prajñāpāramitā ought to be spoken and ought to be received; it is the mother of all buddhas, the mother of all bodhisattvas, and the source from which supernatural powers arise."
