首楞嚴義疏注經 2.399

2.399

若無明相名不見者，暗時無明應不見暗；若實見暗，只可說無明相，不可說為無見也。

If the absence of the characteristic of light is called not seeing, then when in darkness without light, one should not see darkness. If one truly sees darkness, one can only speak of the absence of the characteristic of light, but cannot speak of the absence of seeing.
