JustStunned posted a great quote by the one, wise Buddha... similar to the quote 25yrsmlc posts from time to time, as to how acts of anger are often destructive to us:

(paraphrased) "Acting out [in a negative / destructive way towards someone in retaliation] is like setting yourself on fire to get smoke in their eyes."

So as similar, the following:

"Holding on to anger is like grasping a hot coal with the intent of throwing it at someone else; you are the one who gets burned." -- Siddhartha Buddha
