That which is at the center of the Sacred Space within my heart,
is the very same which is in the sun, which is in the earth,
in the heart of every living being.
~ from Chandogya
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.
