Listen, sometimes if you do become angry, never mind. Just be angry. But it should not stay in your head for long. It should just come and go.
Anger is necessary and essential also at times. So let it be.
If it is for a good cause, and your anger does something good to people, then it is okay. But if your anger is cutting your own head, your own finger, and if it is bothering you, then it is not good and you should take a look at it.
Do you know why you get angry? It is because, either you find others are wrong, or you find you are wrong and you are angry at yourself.
That is why this wisdom is good for you as it helps tame your mind.
If you are pampered too much then you do not realize what you have, and you do not see what you are.
So nature gives you the right lesson at the right time and makes you wake up to the reality
