Anger is perhaps the oldest and most primitive emotion. Anger is easy to recognize in others, but not always in ourselves. Anger ultimately serves a purpose: that of self-preservation. When we sense a threat to our well-being, we become angry in an effort to “get even” with the situation. This is not to say that anger is bad or wrong.
Dealing with anger is often a useful and important emotion, however, left unchecked it can get the best of us and takes us out of the present moment. Anger can ruin relationships, resulting in unnecessary suffering. At its core, anger is about conflict: conflict with others, ourselves, or situations.
To quote Zen Buddhist monk Thich Nhat Hanh from his book Taming the Tiger Within
“When you say something unkind, when you do something in retaliation, your anger increases. You make the other person suffer, and they try hard to say or do something back to make you suffer, and get relief from their suffering. That is how conflict escalates.”
