仁王護國般若波羅蜜多經疏 3.184

3.184

解曰：如是無量者，明所聞也。謂波斯匿王，如舊經云行十地行，地上隨應常見諸佛。今覩神變見大小身，各各宣說般若波羅蜜多導諸大眾，云無量矣。不可識識者，淺近之識所不能識。不可智知者，下劣之智所不能知。顯所說法，多無量故、深不測故、非識知故。從此第三正問奉持。

Explanation: “Such immeasurable” clarifies what was heard. That is to say, King Prasenajit, as the old sūtra states, practiced the practices of the ten bhūmis, and on the bhūmis one constantly sees buddhas as appropriate. Now beholding the supernormal transformation, he saw great and small bodies, each expounding prajñāpāramitā to guide the great assemblies; hence he says “immeasurable.” “Cannot be cognized by consciousness” means shallow consciousness cannot cognize it. “Cannot be known by cognition” means inferior cognition cannot know it. This reveals that the Dharma taught is exceedingly immeasurable, unfathomably deep, and beyond the reach of consciousness and ordinary cognition. Next, the third: the formal question on upholding.
