Anger is a very intense feeling that can really pull us out of ourselves. Sometimes we feel that this is due to others. Yet the anger relates only to ourselves and the way we think. No one else is responsible for our actions except us. The others do not make us angry, but we ourselves.
The other characteristic of anger is that it is a secondary emotion. That is, we will first feel wounded, crowded, wronged, and then we will show our anger. Maybe because all previous feelings are considered “weaknesses”.
