Why do you see the speck in your neighbor's eye, but do not notice the log in your own eye? Or how can you say to your neighbor, "Friend, let me take the speck out of your eye," when you yourself do not see the log in your own eye? You, hypocrite, first take the log out of your own eye, and then you will see clearly to take the speck out of your neighbor's eye.

Jesus

The faults of others are easier to see than one's own; the faults of others are easily seen, for they are sifted like chaff, but one's own faults are hard to see. This is like the cheat who hides his dice and shows the dice of his opponent, calling attention to the other's shortcomings, continually thinking of accusing him.

Buddha
