仁王般若經疏 2.127

2.127

"If a bodhisattva is without reception and without written words, and cultivating apart from written words and not non-written words, cultivates written words by means of non-cultivation, they attain the true nature of prajñā, prajñāpāramitā. Great King! If a bodhisattva protects the buddhas, protects the conversion of sentient beings, and protects the practices of the ten stages, it is like this."
