仁王護國般若波羅蜜多經 1.67

1.67

"Great King! One who cultivates dharmatā cultivates it just as with written words. Dharmatā is the mother of wisdom of all Buddhas, the mother of fundamental wisdom of all sentient beings; this is called the substance of all-knowledge. When the Buddhas have not yet attained Buddhahood, it serves as the mother of wisdom for the future Buddhas; when the Buddhas have already attained Buddhahood, it is all-knowledge. Unattained, it is nature; already attained, it is wisdom. The prajñā of the three vehicles neither arises nor ceases; its self-nature is eternally abiding. In all sentient beings, this is the nature of awakening. If a bodhisattva does not cling to written words nor depart from written words, has no characteristics of written words yet is not without written words, and can cultivate in this way without seeing the characteristics of cultivation, this is called one who cultivates written words, and they are able to attain the true nature of prajñā. This is Prajñāpāramitā.
