This is partly where anger comes from. The impulse that feeds anger is the desire for things to be different from what they are. How silly that we trouble ourselves trying to alter reality and bend it to our wishes. This is sure path to disappointment and destruction. In this respect, anger is a reflection of how attached we are to the illusions of the world and the self. The higher the stakes, the more severe our emotional response. This is why anger often comes about at times when it would seem most important for it not to. We sabotage ourselves with anger when we are most in need of a compassionate attitude towards the self.
