So Muman, anger is a human emotion. Are you saying we should never get angry? Isn't there a time and place for everything? Also, if there's no anger, or hatred of evil and injustice, what motivates good people to take a stand and to do what's right?
I can understand not being consumed by your anger.
Lisa,
I am not covering the entire topic. I am currently listening to the shuir which I linked to above.
All emotions are provided to the soul as ways to accomplish the mission which we are given life for. There is a time and a place for every emotion. A wise person is one who is in control of his emotions. Jewish wisdom teaches that anger does have a time and place, for instance when a child runs into the street while cars are passing. It is essential for a parent to get angry at the child in order to rebuke him/her. There are other places where anger is appropriate, but this anger must not consume, it must be to correct the behaviour of others.
If you are interested you should follow some of the links which I provided. That Chabad link explains how Moses, our Teacher, was punished because of his tiny expression of anger expressed by hitting the rock instead of talking to it. This is a a complex issue and I will certainly not be able to explain everything about it.
I just wished to second the original post which I believe is an important aspect of our Torah.
