Anger comes in a flash and it overpowers the whole thought process. When one is angry, one also loses rationality and affinity, and as such the ultimate impact becomes highly dangerous not only for the person concerned but also for his surroundings.
IN ALL religions, anger is regarded as the basic reason of destruction. It is a serious vice and hence the best way to go ahead for a peaceful life is to get away from it.
