辨差別中，表色者，謂業用為作，動轉差別者，業用者，思業也，由此思業為作故，諸有形色動轉差別說名表色。基公牒論文業用為依，釋中言：以此言以此為依，未知何正？

In distinguishing the differences: 'Revelatory form refers to action-efficacy as its operation, the distinction of movement.' 'Action-efficacy' refers to intentional action (cetanā-karman). Because of this intentional action serving as the operation, any distinction of movement in shape-forms is designated as revelatory form. Master Ji cited the treatise text as 'relying on action-efficacy' (業用為依) and noted in his commentary that it reads 'relying on this' (以此為依); it is not known which is correct.
