What a terrible thing to carry around with you. It's heavy and it hurts. As the old Buddhist saying goes; holding on to it is like grasping a hot coal with the intent of throwing it at someone else, however you are the one who gets burned. Anger.
Mark Twain said anger is an acid that can do more harm to the vessel in which it is stored than to anything on which it is poured. And Einstein believed that anger dwells only in the bosom of fools. I think that it's true, anger can be quite harmful if stored or held on to. So, what are you to do with it?
There are many ways to cope with or release anger; meditation, writing, exercise, counselling/therapy, listening to music, talking about it, screaming into a pillow. But have you ever considered just how powerful and useful anger can be?
I remember feeling really angry one day, and I stormed out into the backyard, found a garden bed overgrown with weeds and kneeled down then began to vigorously rip out the weeds. I didn't stop until they were all clear, and then I found that I was too! My anger had subsided. So, this proves that you can get creative with your anger, you don't need a punching bag.
Anger is a natural source of energy, and is best utilised not stored. It can also be a positive. Anger can be used as motivation, and is actually quite powerful. It's not really a bad thing until you choose what to do with it. The outcome of anger can be good.
Anger doesn't just have to make you angry. It exists in order to encourage action, so don't hold on to it. Use it.
