仁王護國般若波羅蜜多經疏 2.227

2.227

解曰：能斷三障者，如下經云「七地斷諸業果細現行相，八地斷諸功用，九地斷無礙障。」斷此三障也。色心習氣者，通種現也，下廣明矣。謂所知障，十地於前六地各治一分。色心麁重彼障下品，故此三地各別斷故。從此第三結申利他。

Commentary: Regarding 'capable of severing the three obstacles': as the sūtra states below, 'The seventh bhūmi severs the subtle active characteristics of karma and fruit; the eighth bhūmi severs all effort; the ninth bhūmi severs the obstacle to unobstructedness.' These are the three obstacles severed. Regarding 'the latent impressions of form and mind': they comprise both seeds and active manifestations, as explained extensively below. That is, regarding the obstacles to the knowable, on the ten bhūmis one eliminates a portion on each of the preceding six bhūmis; the heavy encumbrances of form and mind are the inferior grades of those obstacles, and thus these three bhūmis sever them distinctly. Hereafter, the third [part] concludes by stating the benefiting of others.
