Why do we judge our neighbors? ( St. Seraphim of Sarov )

Why do we judge our neighbors? Because we are not trying to get to know ourselves. Someone busy trying to understand himself has no time to notice the shortcomings of others. 
 Judge yourself — and you will stop judging others. 
 Judge a poor deed, but do not judge the doer. It is necessary to consider yourself the most sinful of all, and to forgive your neighbor every poor deed.

 One must hate only the devil, who tempted him. It can happen that someone might appear to be doing something bad to us, but in reality, because of the doer's good intentions, it is a good deed. Besides, the door of penitence is always open, and it is not known who will enter it sooner — you, "the judge," or the one judged by you.
