4.149

二十四、「三染，餘二種」等者，彼云無明、愛、取唯通不善、有覆無記，即此三染。前第四門，說四雜染；今言三者，此實前假，義別故。其不善中，通染及無覆無記。彼云行唯善、惡。有通善、惡、無覆無記。七分位中亦起善、染，故名通二。此實無記依五當生，故無過失。

24. Regarding "Three are defiled, the rest are of two kinds," and so forth: that [text] says that ignorance, craving, and grasping only extend to the unwholesome and the obstructed-indeterminate; these are the three defiled. Earlier, in the fourth approach, four defilements were spoken of; now stating three, this is real whereas the earlier was provisional, because the meanings differ. Within the unwholesome, it extends to the defiled and the unobstructed-indeterminate. That [text] says formations are solely wholesome and unwholesome. Existence extends to wholesome, unwholesome, and unobstructed-indeterminate. In the states of the seven, wholesome and defiled also arise; hence they are named extending to both. These are actually indeterminate relying on the five yet to be born; hence there is no fault.
