Buddha beautifully talks about Anger as “Drinking poison and expecting other person to die”. It is one of the three poisons that Buddha talks about. Anger is best example of negative emotion which can never solve any problem but every day we use it to solve problems. It creates an illusion of having power and gives comfort of solving. If fed with more thoughts, all that it is capable of doing is to grow many other supporting negative emotions like resentment, frustration and hatred. If the receiver of anger is not conscious it will agitate them too.
Anger stems from your mental personal assessment of situation and making assumptions, evaluations, judgments or interpretations of situations. Anger is caused by an obstacle to your desire. The level of anger is directly proportional to your level of desire. It makes you think that someone else is attempting to hurt you or by not responding the way that you want them to respond to.
Anger is a temporary solution for mind and ego. You don’t need to face the person you are angry with until they respond or you expect them solve the cause of your anger. It is ego’s way of making you feel rightful and get you a feeling of superiority by shifting the ownership of problem.
There can never be a rightful anger. However we as human beings it is impossible not to use this as self defense tool. But if you just become aware of anger and just tell yourself “Oh I am feeling angry. Anger wont solve the problem” next time when you see yourself angry, it will go away. Ego will need the anger to survive. It will try to convince you that what you are doing is right. If you give importance to ego mind it will become the poison that Buddha said.
Remember that best fighter is never angry. I am not saying not to fight for your rights. But never use anger to fight.
