Holding anger is a poison. It eats you from the inside. We think that hating is a weapon that attacks the person who harmed us. But hatred is a curved blade. And the harm we do, we do to ourselves.
"Where"er a noble deed is wrought,
Where"er is spoken a noble thought,
Our hearts in glad surprise
To higher levels rise."
-Henry Wadsworth Longfellow (1807-1882)
