成唯識論了義燈 5.3

5.3

問：《疏》云：若四受俱，則金剛心非頓斷過者，說與捨受俱，豈不漸斷，以易地捨故？答：云若喜等俱，必隨地別，染法俱斷如六識故。若捨受俱，即可頓斷，如第八識捨俱頓斷。其理極成，故無有失。

Question: The Commentary says: "If it were concurrent with four sensations, there would be the fault that the adamantine mind (vajrasaṃbhadhyāna) could not sever them all at once." But regarding its being concurrent with the sensation of equanimity, does it not sever them gradually, because equanimity changes with the stages? Answer: If it were concurrent with joy and so forth, it would inevitably vary according to the stages, and defiled dharmas would be severed together [with them], just as in the six consciousnesses. If it is concurrent with the sensation of equanimity, then it can indeed be severed all at once, just as the eighth consciousness, being concurrent with equanimity, is severed all at once. This principle is thoroughly established, so there is no fault.
