Only so much until it's gone...

It is important not to suppress your feelings altogether when you are angry. It is equally important to avoid terrible arguments or expressions of outrage. You should steer clear of emotionally damaging behaviour. People forgive, but it is best not to stir things up to the point at which forgiveness is required. When you are raging, you need the love of other people, and yet furor fosters actions that destroy that love. It's like sticking pins into your own life rafts. Then, all that's left, is for the conscious mind to intervene. One is not helpless. Holding a grudge and harbouring resentment is poison to the soul. Get even with people, but not those who have hurt us, forget them, instead get even with those who have helped us.
