大方廣佛華嚴經隨疏演義鈔 74.18

74.18

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.
