1.726

雖云磨鏡，却是磨塵。所言修道，秖是遣妄。夫鏡性本明，非從外得，塵覆則隱，磨之則顯，隱顯雖殊，明性不異。今謂人執、法執是垢，尋伺如實是磨，真心本覺是明，人法二空是現。

Although it speaks of polishing the mirror, it is actually polishing away the dust. What is called cultivating the Path is merely dispelling delusion. Now, the nature of the mirror is fundamentally luminous, not obtained from outside; when dust covers it, it is obscured, and when polished, it is revealed. Although obscured and revealed differ, the luminous nature does not vary. Here, the grasping at persons and grasping at dharmas are the grime; investigative and realistic contemplations are the polishing; the true mind of original enlightenment is the clarity; and the two kinds of emptiness of persons and dharmas are the appearing.
