Anger is essential for you. But how much you need you should know. Anger may be the form of the ego. One need to analyze the anger. Why for are you angry whether because someone told some bad words about you because someone pointed out my mistake. But when one has the feeling that I am nothing then anger will angrily change the direction.
Where as if someone is doing some injustice to someone and the anger does not arise in you then is it good not to have it.
So guys use it judiciously rather analyze the source of anger and go about it. Should it not be like a pinch of salt which when you put makes your curry tasty.
