首楞嚴義疏注經 4.64

4.64

如是三相互相擾惱、互相雜亂，形待不息，遂成勞倦，如勞目睛則有狂華。三相虛妄染污真性，故名為塵。汩清淨體令失明潔，故名為濁。濁之麁細名相五重，如下廣辨，皆由此三而為根本也。

In this way, the three marks mutually disturb and confuse one another, their contrast and opposition never resting, and thus fatigue ensues—just as when eyes are fatigued, wildly dancing flowers appear. The three marks, being false, defile the true nature, and therefore are called 'dusts'. They pollute the pure substance and cause it to lose its clarity and cleanliness, and therefore are called 'turbidity'. The coarse and subtle names and marks of turbidity have five layers, as will be extensively analyzed below; all have these three as their root.
