"The Usefulness of Suffering"
The substance that can neutralize anger is compassion. If you know how to generate the energy of compassion, it can transform your anger. When you can see another persons suffering, when you have understood their suffering, suddenly compassion is born in you. When compassion is born, you don't suffer anymore when you look at the person who has harmed or hurt you. You no longer want to punish that person. Instead you want to help them suffer less. We can speak of the goodness of suffering. Suffering brings about understanding and compassion, which are the true foundations of happiness".
