Spite is anger which is afraid to show itself, it is an impotent fury conscious of its impotence.
The more anger towards the past you carry in your heart, the less capable you are of loving in the present.
Holding anger is a poison. It eats you from 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.
