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.
Art arises from a spiritual longing that all people share: to make our mark on the world and to spend our life energy in a work that rises above the mundane, adding grace to existence. We respond to the light of the world around us by giving expression to our own inner light, and when the two are on the same wave-length, the world seems more brilliant and finely focused.
