16.6

能盡彼無漏者，彼是所治也，無漏能治也。謂無漏業能盡彼前黑等三業，名非黑非白。不染污故名為非黑，不招白異熟故名為非白。論云：「此非白言是密意說，謂佛於彼《大空經》中告阿難陀：『諸無學法純善純白，一向無罪（解云：既言無學純白，故知無漏法名非白者是密意說，不顯了也）。』」

[Regarding] 'and the undefiled that can exhaust them': 'Them' refers to what is to be countered; 'undefiled' is the counteragent. That is, undefiled karma can exhaust those previous three karmas, black and the rest, and is called neither black nor white. Because it is not defiled, it is called non-black; because it does not incur white maturation, it is called non-white. The treatise states: 'This expression "non-white" is an intentional statement, as when the Buddha in the Mahāśūnyatā-sūtra addressed Ānanda: "All the dharmas of an aśaikṣa are purely wholesome and purely white, entirely without fault" (Explanation: Since he says that the aśaikṣa is purely white, we know that calling undefiled dharmas "non-white" is an intentional statement, not an explicit one).'
