成唯識論述記 6.942

6.942

述曰：此中忘念，念為體者，不與別境中念俱；通癡分者，故得相應。惠准此知，亦有癡分故。此二合說，故言「染念、慧」等。問：忿緣現在，念緣曾習，云何此二說得俱生？

[The Commentary states:] Here, when forgetfulness has mindfulness as its essential nature, it does not co-occur with the mindfulness of the specific-object [factors]; but since it also comprises a portion of delusion, it can therefore be associated with it. Discernment should be understood by analogy with this, as it also has a portion of delusion. These two are stated together, hence it is said: "defiled mindfulness and discernment," and so forth. Question: Anger takes the present as its object, whereas mindfulness takes what has been previously practiced as its object; how can these two be said to be capable of co-arising?
