3.247

二十七、染不染，唯識云：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。唯識云：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。

Regarding 'Twenty-seventh, defiled and undefiled,' the Vijñaptimātratāsiddhi says: Ignorance, craving, and clinging only pertain to the unwholesome and the obscured-unrecorded; these three defilements were previously called the four afflictive defilements in the fourth gateway. Now it says three because these are real whereas the previous were nominal, their meanings being distinct; among the unwholesome, it pertains to both the defiled and unobscured-unrecorded. The Vijñaptimātratāsiddhi says: Volitional formations pertain only to wholesome and unwholesome; existence pertains to wholesome, unwholesome, and unobscured-unrecorded; in the phases of the seven branches one also gives rise to wholesome and defiled, and hence it is called pertaining to both. This is in reality unrecorded, but because it relies on the five to be born in the future, there is no fault.
