仁王護國般若波羅蜜多經疏 2.623

2.623

解曰：法門非一者，佛對根宜，當病設藥，一音演說隨類各解，故非一也。亦非無量者，當病之教雖等塵沙，隨所證理，非無量也。又以所證就有情心，一一門中皆得解脫，故非一也。有情畢竟行無不修、障無不盡，至無上覺佛果圓滿，非無量矣。從此第三總徵所以。

Explanation: "The Dharma gates are not one": because the Buddha responds to the suitability of faculties, prescribing medicine appropriate to the illness, and expounds with a single voice while each type understands accordingly, they are not one. "Nor are they immeasurable": although teachings tailored to illnesses are equal to the sands of the dust, in accordance with the principle realized, they are not immeasurable. Furthermore, taking what is realized and approaching the minds of sentient beings, liberation is attained in each and every gate; hence they are not one. For sentient beings, ultimately there is no practice they do not cultivate and no hindrance they do not exhaust, reaching anuttarasaṃbodhi where the buddha fruit is perfected; hence they are not immeasurable. Next, the third section generally investigates the reason.
