What would Marcus Aurelius say about anger?

Anger pretends to lend you strength, yet it first takes your judgment hostage. You think you are answering another man's wrong, but in that moment you hand him rule over your inner state. What an unworthy surrender. If he acted from ignorance, confusion, greed, or wounded pride, then he has already injured himself. Why imitate the disease you condemn? Pause before the heat becomes speech. Ask what has truly happened and what part your own pride has added. Most offenses wound less than the story of insult you build around them. This does not mean approving what is unjust. It means opposing it without becoming disordered yourself. Correction is possible in a calm mind; revenge belongs to a fevered one. Do not make your soul a lodging for another person's fault. Observe how quickly a flame dies when it is not fed.
