大方廣佛華嚴經隨疏演義鈔 81.8

81.8

疏「是知玄道」下，結成正義。言「妙悟」者，即能契。是由能契即真，方得成此所契即真，即是性淨。即妄即真，生無生矣，豈非齊觀？齊觀一味，能所兩冥，故全真性以為我體。真既湛然，故知雙林應滅非滅，以常住故。言「無滅」者，本寂滅故。然此亦即〈妙存〉中文，上意業中用其一半，彼已具引。今側用兩句，謂彼「天地與我同根，萬物與我一體」，今順經文，以真如等為涅槃本。

On the commentary’s "Hence we know that the mysterious Dao..." onward: this concludes and establishes the correct doctrine. The phrase "marvelous awakening" refers to that which is capable of tallying [with reality]. It is because that which is capable of tallying is identical to the real that that with which it tallies can be established as identical to the real, which is precisely the purity of nature. The deluded being identical to the real, arising is non-arising—how could they not be viewed as equal? Viewing them as equal and of one taste, both subject and object become imperceptible, so that one takes the complete true nature as one's own essence. Since the real is ever serene, we know that the responsive extinction between the twin trees was not extinction, because it is eternally abiding. The phrase "without extinction" is used because it is fundamentally quiescent extinction. However, this is also a passage from the chapter "Marvelous Preserving" (Miaocun); half of it was used above under mental karma, where it was already cited in full. Here it obliquely uses two sentences, referring to that text’s "Heaven and earth share the same root with me; the ten thousand things are of one essence with me"; here, in accordance with the sūtra text, it takes tathatā and so forth as the root of nirvāṇa.
