Happiness arises as a result of different causes and conditions. If you harm someone out of anger, you may feel some superficial satisfaction, but deep down you know it was wrong. Your confidence will be undermined. However, if you have an altruistic attitude, you’ll feel comfortable and confident in the presence of others.
Dalai LamaThe most important benefit of patience consists in the way it acts as a powerful antidote to the affliction of anger.
