金剛三昧經論 2.131

2.131

論曰：此下第三明空不無真而不有真義，先問、後答。問意而言：凡言有無必也相對，不有必無、不無即有。若言不無真實之理，則應是有真實之理。凡諸學者每作是計，為遣彼執故作是問。

The treatise states: From here below, the third part explains that emptiness is not devoid of the real yet does not have a real [nature]. First is the question, then the answer. The intent of the question says: whenever existence and non-existence are spoken of, they are necessarily relative; what is not existent is necessarily non-existent, and what is not non-existent is immediately existent. If one says that it is not devoid of the principle of the real, then there should be an existent principle of the real. Ordinary scholars constantly form this conceptualization; in order to eliminate their attachment, this question is raised.
