論。云何為二至不相應故　述曰。此列名舉辨也。所言麁者。即前三染有心心所法麁顯相故。與心相應者。釋麁義也。謂有境界及有心所與此三種心相應故。所言細者。即後三染無心心所麁顯相故。與心不相應者。釋細義也。謂彼心所及諸境界與三細心不相應故。

Treatise: "What are the two? [The first is coarse, because it is concordant with the mind. The second is fine, because it is not concordant with the mind.]"
Exposition: This lists the names and presents the distinction. What is called "coarse" refers to the preceding three defilements, because they possess the coarsely manifest characteristics of mental dharmas and mental concomitants. "Because it is concordant with the mind" explains the meaning of coarse: it means that objects and mental concomitants are concordant with these three kinds of mind. What is called "fine" refers to the subsequent three defilements, because they lack the coarsely manifest characteristics of mental dharmas and mental concomitants. "Because it is not concordant with the mind" explains the meaning of fine: it means that those mental concomitants and various objects are not concordant with the three fine minds.
