佛說仁王般若波羅蜜經 1.50

1.50

「大王！如如文字修諸佛智母，一切眾生性根本智母，即為薩婆若體。諸佛未成佛，以當佛為智母，未得為性，已得為薩婆若。三乘般若，不生不滅，自性常住。一切眾生，以此為覺性故。若菩薩無受無文字，離文字，非非文字，修無修為修文字者，得般若真性般若波羅蜜。大王！若菩薩護佛、護化眾生、護十地行，為若此。」

"Great King! To cultivate letters as suchness is the mother of all buddhas' wisdom; the fundamental mother of wisdom of all sentient beings' natures is itself the substance of sarvajñā. Before buddhas attain buddhahood, they take their future buddhahood as the mother of wisdom; before it is attained, it is the nature, and once attained, it is sarvajñā. The prajñā of the three vehicles is neither born nor destroyed, and its intrinsic nature is permanently abiding. This is because all sentient beings take this as their awakening nature. If a bodhisattva is without grasping and without letters, free from letters yet not non-letters, cultivating non-cultivation as the cultivation of letters, he will attain the true nature of prajñā, the prajñāpāramitā. Great King! If a bodhisattva protects the Buddha, protects the transformation of sentient beings, and protects the practices of the ten stages, he does so in this manner."
