首楞嚴義疏注經 4.606

4.606

鏡明不動，影像隨形，苟見像之去來而曰鏡之起滅者，倒之甚矣。聲聞無辨，斷常遂迷，故此結勸，不可更言離聲無性。

The mirror's brightness is unmoving, while reflected images conform to the forms. If one sees the coming and going of images and says that the mirror arises and perishes, that is inversion in the extreme. Without discerning sound and hearing, one becomes deluded regarding annihilation and constancy; therefore, this concludes with an exhortation that one must not say again that apart from sound there is no nature [of hearing].
