大方廣佛華嚴經隨疏演義鈔 73.47

73.47

疏「既事理雙遊」下，結成，釋上定無分別，慧觀一相，故不住也。定不壞相，慧不壞諸，故不壞也。又二句中不壞，即不壞相。二句中無分別觀一相故，即不壞性。二句中不壞諸相，故不住理。二句中無分別觀一相，故不住事。故由雙遊，得不壞不住。

The commentary states: "Since both phenomena and principle are coursed in together..." and so forth; this concludes and resolves the explanation that because in samādhi there is no discrimination and in wisdom one contemplates the single characteristic, there is no abiding. Because samādhi does not destroy characteristics and wisdom does not destroy the manifold, there is no destruction. Furthermore, within the two lines, "not destroying" means not destroying characteristics. Within the two lines, because there is non-discriminating contemplation of the single characteristic, that is not destroying the nature. Within the two lines, not destroying the manifold characteristics means not abiding in principle. Within the two lines, non-discriminatingly contemplating the single characteristic means not abiding in phenomena. Thus, by coursing in both together, one attains non-destruction and non-abiding.
