大方廣佛華嚴經隨疏演義鈔 37.45

37.45

疏「見非實者知其即實」者，即諸經意云：若見非實即真，名見非實。下引《中論》即是法品，前〈光明覺品〉已廣引竟。然實有二意：且就一相理實為實，事相非實，即真俗二諦。俗則一切皆俗，佛亦隨俗立名；真則一切皆真，知妄本自真。故雙照為俱存，互奪即雙寂。

Regarding the commentary stating, "Seeing the unreal is knowing it to be identical with the real": this conveys the meaning of various sūtras that if one sees the unreal as identical with the real, it is called seeing the unreal. The subsequent quotation from the Madhyamakaśāstra is from the chapter on phenomena (Dharmaparīkṣā), which has already been extensively quoted in the earlier "Chapter on Awakening through Radiance". However, the real has two meanings: first, in terms of a single characteristic, the reality of principle is the real, and the characteristics of phenomena are unreal; these are the two truths, ultimate and conventional. Conventionally, all things are conventional, and the Buddha also establishes designations following convention. Ultimately, all things are real, knowing that delusion is originally real. Thus, double illumination means both are preserved, while mutual negating means both are tranquil.
