4.39

於不善不共，見俱唯二十者，此明不善心品二十心所俱生也。不善不共者，不共無明也。見者，不善見也。俱者，謂不善心一與不共無明俱、二與不善見俱也。且於不善不共無明心品，必有二十心所俱生，謂大地十、大煩惱地六、大不善地二、及與尋、伺。第二不善見相應心品者，謂此心中或有邪見、或有見取、或有戒禁取，亦有二十心所俱生，名即如前不共品說。於五見中除身、邊見者，此二見是有覆無記見也。問：「此不善見相應心品合有二十一，二十如前，應加不善見，何故俱言二十耶？」答：「非見增故，無有二十一，以即於十大地法中慧用差別，說為見故。見以慧為體，十大地法中慧已攝竟，故不重說也。」

Regarding "In the unwholesome, [associated with] exclusive [ignorance] and with views, there are only twenty": this clarifies the twenty mental factors that arise co-existently in the unwholesome category of mind. "The unwholesome, exclusive" refers to exclusive ignorance (āveṇikī avidyā). "Views" refers to unwholesome views. "With" means that the unwholesome mind arises, first, with exclusive ignorance, and second, with unwholesome views. Now, in the mental category of unwholesome exclusive ignorance, there must be twenty mental factors co-arising, namely the ten great ground [factors], the six great defilement ground [factors], the two great unwholesome ground [factors], as well as investigation and scrutiny. Second, as for the mental category associated with unwholesome views: in this mind there is either wrong view, or attachment to views, or attachment to rules and rituals, and twenty mental factors also arise co-existently with it, whose names are just as described above for the exclusive category. Among the five views, the view of individuality and extreme views are excluded, because these two views are obscured indeterminate views. Question: "Should this mental category associated with unwholesome views not total twenty-one—twenty as before, plus the unwholesome view; why then does it state 'only twenty'?" Answer: "Because a view is not added additionally, there are not twenty-one. It is because a distinct function of wisdom within the ten great ground factors is designated as a 'view'. A view has wisdom as its essence; and since wisdom is already included within the ten great ground factors, it is not stated again."
