On Anger By Rabbi Ira Stone

Anger results from our inability to admit the disparity between what we want and what is. It is a consequence of the impossibility of perfection in the created world in which the idea of perfection nevertheless exists...Following the example of the prophets, each of us has a mandate to assuage the destructive energy of anger in our selves, in other people and in God. We also have a mandate to accept the life-giving energy that emerges from the anger that is constructively channeled, whether it comes from God or from people.
