維摩經玄疏 4.98

4.98

二、約理教明本迹者，此經云「三轉法輪於大千，其輪本來常清淨」，今言不思議之理本，即是不思議二諦之理事，通名為理，理即本也。不思議之教迹者，即是大聖八音敷演不思議能詮二諦之教迹也。所詮不思議二諦之理，即是理本；能詮之教，即是事迹。是則由理本故有教迹，尋教迹以得理本。本迹雖殊，不思議一也。

2. Clarifying origin and traces in terms of principle and teaching: This sūtra says: 'Turning the wheel of Dharma thrice in the great chiliocosm, that wheel is originally and constantly pure.' Now, what is called the origin of the inconceivable principle is the principle and phenomena of the inconceivable two truths, collectively termed 'principle'; principle is the origin. The traces of the inconceivable teaching refer to the great sage's exposition through the eight voices of the traces of the teaching that can express the inconceivable two truths. The principle of the inconceivable two truths that is expressed is the origin in principle; the teaching that expresses it is the trace in phenomena. Thus, due to the origin in principle, there are traces in teaching; by following the traces in teaching, one finds the origin in principle. Though origin and traces are distinct, inconceivably they are one.
