3.188

已下破境生。初句牒，識因下根境俱亡破。聲能生識，何假於聞，此亡根也。若無於根，聲亦不有，此亡境也。根境俱亡，識從誰生？

From here onward is the refutation of arising from the objective realm. The first sentence cites [the thesis]. The sentences from 'consciousness existing due to sound' onward refute it on the ground that both faculty and objective realm vanish: if sound could produce consciousness, what need would there be to rely on hearing? This causes the faculty to vanish. If the faculty does not exist, sound does not exist either; this causes the objective realm to vanish. When faculty and realm both vanish, from what is consciousness produced?
