成唯識論演祕 5.323

5.323

五識不俱而有二義：一、五總不與輕安俱也，由有苦故；二、但苦受相應不俱，非餘捨、樂不容俱也。前釋善也，故《疏》下云：然實菩薩至但除苦受。若准後解以顯菩薩五得有訖，然實等文豈不煩賸，故知前善。

That it does not accompany the five consciousnesses has two meanings: first, the five as a whole do not accompany pliancy, because of the presence of pain; second, it is merely that association with painful feeling does not occur concomitantly, not that the remaining neutral and pleasant [feelings] cannot be concomitant. The former explanation is the good one; therefore the Commentary below says: "However, truly bodhisattvas... up to... merely exclude painful feeling." If one relies on the latter explanation to show that the bodhisattva's five [consciousnesses] can have it, would not the text "However, truly..." and so forth be superfluous? Thus we know the former is good.
