We are not masters of our emotions. The source of our emotions is unconscious, a short circuit of psychic energy from the autonomous center of our being. Once this energy is released it needs to go somewhere. Even when the apparent cause or trigger is standing right in front of you, the true source is still deeply within us, out of reach of all conscious will to control. In anger, we are projecting. I find the idea of mastering anger as absurd as mastering love. This is an ego-trap. All anger is a symptom of an over inflated ego: a result of our frustrated need to coerce the environment beyond reasonable limits. You can get rid of anger by seeing it for what it really is. Then the unconscious projection will be withdrawn this energy will then be conserved for growth of your non-ego Self instead of wasted on meaningless ego inflation.
