首楞嚴義疏注經 4.597

4.597

斥破意者，此聞若因聲有，則不離聲。若離聲有，此是真聞。汝今但執隨聲之聞，此聞既不離聲，只合是聲，不合名聞。又言是聲、又言是聞，既隨言印順，故成矯亂。

The purport of rebuking and refuting is: if this hearing exists dependent on sound, then it is not apart from sound. If it exists apart from sound, this is true hearing. You now merely cling to a hearing that follows sound; since this hearing is not apart from sound, it should only be sound, and should not be called hearing. Yet you say it is sound, and you also say it is hearing. Since you merely chimed in and agreed following words, it becomes equivocation.
