大般涅槃經義記 5.43

5.43

次明惠行，於中有二：一明行體、二「無垢」下嘆經令學。前中復二：一因分所修、二「則得住於無畏地」下果分所成。

Next, the practice of wisdom is explained, within which there are two parts: first, explaining the substance of the practice; second, from "without defilement" onward, praising the sūtra to cause one to learn it. In the former, there are again two parts: first, what is cultivated in the causal stage; second, from "then one can abide on the stage of fearlessness" onward, what is accomplished in the fruition stage.
