7.20

可訶等者。明不受之由。亦是以果驗因成不受義。意云：果若有漏則知受福，是可訶責。果既無漏則知不受，云何可訶？

"Censurable," and so forth, clarifies the reason for not receiving. This also examines the cause through the fruit to establish the meaning of not receiving. The intended meaning is: If the fruit were contaminated, then one would know that receiving merit is censurable. Since the fruit is uncontaminated, one knows there is no receiving; how could it be censurable?
