金光明經文句記 1.146

1.146

三、「此」下，結境智相稱。如《法華》云「唯佛究盡諸法實相」。權實之理何有盡極？良由佛得無盡之智方能究盡。今亦如是。二乘下地智有限量，是故不測無涯之涯、無底之底。

Third, from "This" below, concluding the correspondence between object and wisdom. As the Saddharmapuṇḍarīka Sūtra says: "Only a Buddha can exhaust the real mark of all dharmas." How could the principle of the provisional and real have an end? It is truly because the Buddha has attained inexhaustible wisdom that he can exhaust it. The present case is also like this. The wisdom of the two vehicles and lower grounds has limits and measures, and therefore cannot fathom the boundary without boundary, the bottom without bottom.
