仁王護國般若波羅蜜多經疏 2.71

2.71

解曰：信心澄淨，眾善之本。若常信者無已比方，但取於經一念淨信勝前福故。何況等者，少信尚勝，何況有能受持讀誦心生正解，勝無等故。受持等者，受謂領受，持謂不忘，對文背本，讀誦異也。如《辯中邊論》十法行頌云「書寫以供養，施人聽故讀，受持正開演，諷誦及思修。」前八為聞，後二思修，謂即三慧。此有彼四，三聞一思，舉其少解即勝前故。

Exposition: A faithful mind that is clear and pure is the root of all goods. If one has constant faith, there is no comparison; taking only a single thought of pure faith in the sūtra surpasses the previous merit. As for "let alone," even a small amount of faith is still superior, so how much more so for one who can uphold, read, recite, and generate correct understanding in mind; its superiority is incomparable. As for "upholding" and the rest: "accepting" means receiving it, "upholding" means not forgetting it, and facing the text versus reciting from memory marks the difference between reading and chanting. As the verse on the ten dharma-practices in the Madhyāntavibhāga-śāstra says: "Copying to make offerings, giving to others, reading so that they may listen, upholding, correctly expounding, reciting, and contemplating and cultivating." The first eight are hearing, and the last two are contemplation and cultivation, which are the three wisdoms. Here four of those are present: three of hearing and one of contemplation; mentioning even their slight understanding already surpasses the former.
