首楞嚴義疏注經 2.533

2.533

心境不同，能所殊體，故云必異。明見若雜，各失其義，明則非明，見亦非見。二義既失，名字亦亡，猶如微塵與水相和，但名泥團，不名塵水。明見既失，將何名和？故云非義也。

Mind and object are not the same, and subject and object are distinct in substance; hence it says 'must be different.' If light and seeing are mixed, each loses its own meaning: light is then not light, and seeing is also not seeing. Both meanings being lost, their names also perish, just as when fine dust blends with water, it is only called a lump of mud, not dust and water. Since light and seeing are both lost, what would be called blending? Therefore it says 'illogical.'
