仁王般若經疏 3.52

3.52

"The Buddha told..." onwards is the third major section within the chapter, the Tathāgata's endorsement. In the text there are two [parts]: First, he endorses it, hence saying "So it is, so it is!"; second, from "As the kings have said..." onwards, he encourages that it ought to be spoken and ought to be received and upheld, praising prajñā as the source of all sages with three clauses: it is the mother of all buddhas, the mother of all bodhisattvas, and the mother of all supernatural powers.
