大方廣佛華嚴經隨疏演義鈔 10.25

10.25

疏「六事能隱理門」，即隨緣之中別義。以隨緣成事，此事遍於真理，故事顯理隱也。

Regarding the Commentary's 'Sixth, the gate of phenomena being able to conceal principle': this is a distinct meaning within concordance with conditions. Because [dharmas] form phenomena through concordance with conditions, and these phenomena pervade true principle, phenomena are manifest while principle is concealed.
