Emotions are like fragrance. For one, they are temporary. And for another, they are already out of our body, about to be wafted away. But they still affect our senses and make us feel that we are defined by that fragrance.
When we feel anger, it is already exposed and ready to be dissipated. Yet we define the 'remaining' ourselves as 'angry'. When I pass wind, is there any point defining myself by its smell and saying: "Oh, I am such a stinky person." It is gone.
While the fragrance is passing, just deal with it. Let's not define ourselves by it.
