Master your emotions
Introducing conscious awareness to facial expressions can help one override and control their emotions. If you put on your face one of the universal expressions you will turn on the physiology of emotion. You will begin to experience that emotion. So the face is not simply a display system that tells you what’s happening inside me. I can self generate any emotion by making the movements on my face. The way in which we can improve our emotional life is to introduce conscious awareness into the process and that will take practice since nature did not want you to do that’ so you have to do it yourself.
