Do not have opinions in other people’s actions. When we see defects in others, people in general but particularly those who have entered the Dharma, who are the banner of the monastic robes, are the support for the offerings of gods and men alike, we should understand that it is the impurity of our perception which is at fault. When we look into a mirror, we see a dirty face because our own face is dirty. In the same way, the effects of others are nothing but our impure way of seeing them. By thinking this way, we should try to rid ourselves of this perception of the faults of other, and cultivate the attitude whereby the whole of existence, all appearances, are experienced as pure.
