3.231

詳曰：此明二分，言能緣相即見分心，非約見分依心上立。若別立者，三分何別？如前見分名為行相，豈見分上而別說耶？由斯正量有能緣相，故知諸德說不乖論。

Examination: This explains the two aspects: the phrase "aspect capable of cognizing" refers precisely to the mind of the vision aspect, and is not established on the mind on the basis of the vision aspect. If it were established separately, how would it differ from the three aspects? As stated previously, the vision aspect is called the cognitive aspect; could it be spoken of separately on top of the vision aspect? Since the Sammatīyas possess the aspect capable of cognizing, one knows that the statement of the various venerable masters does not contradict the Treatise.
