Whenever
you think God has shown you other people's faults, take care: your
own judgment may well be at fault. Say nothing. And if you do
attribute any vice to another person, immediately and humbly look for
it in yourself also. Should the other person really possess that
vice, he will correct himself so much the better when he sees how
gently you understand him, and he will say to himself whatever you
would have told him.
