大方廣佛華嚴經隨疏演義鈔 74.18

74.18

疏「三約雙遮」下，文有二意：一前明相即，故得雙遮。謂相本是異，今即性故，無有異也，故非異，性本是一，今即相故，無有一也，故非不異。二「又相非相」下，明當相自離，故得雙非。「故離二邊」下，結成玄旨。

Under the commentary's "third, in terms of mutual negation," the text has two meanings: First, previously it clarified mutual identity, and therefore attains mutual negation. That is to say, marks are originally different, but now being identical with nature, there is no difference; hence they are not different. Nature is originally one, but now being identical with marks, there is no oneness; hence it is not not different. Second, under "Furthermore, marks are non-marks..." it clarifies that being fundamentally separate within their very marks, they therefore attain mutual negation. Under "Therefore, leaving the two extremes..." it concludes the profound purport.
