by Thich Nhat Hanh: Practical methods directly from Buddha
When someone says or does something that makes us angry, we suffer. We tend to say or do something back to make the other suffer, with the hope that we will suffer less. We think, “I want to punish you, I want to make you suffer because you have made me suffer. And when I see you suffer a lot, I will feel better.”
The Buddha gave us very effective instruments to put out the fire in us: the method of mindful breathing, the method of mindful walking, the method of embracing our anger, the method of looking deeply into the nature of our perceptions, and the method of looking deeply into the other person to realize that she also suffers a lot and needs help. These methods are very practical, and they come directly from Buddha.
If your house is on fire, the most urgent thing to do is to go back and try to put out the fire, not to run after the person you believe to be the arsonist. If you run after the person you suspect has burned your house, your house will burn down while you are chasing him or her. That is not wise. You must go back and put out the fire. So when you are angry, if you continue to interact with or argue with the other person, if you try to punish her, you are acting exactly like someone who runs after the arsonist while everything goes up in flames.
