People have always wondered at the saints, that they are able to walk around serene, whatever happens. But that is because they can choose where they'll be. They don't have to be angry. You see the difference between having scattered emotions and having a fully vibrating, controlled emotional body. This body is made from energy created from choice, from the effort involved in making choices. But it is necessary to practice; then something is possible.
Prayer is sitting in the silence until it silences us, choosing gratitude until we are grateful, praising God until we ourselves are a constant act of praise.
