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.
The saints speak of something they call the inextinguishable light. It is a light not of the eye but of the heart that never ceases to walk in purity and clearness. It swiftly leaves the darkness behind, and constantly strives towards the day's height. Its constant quality is to be continually purified. This is the light of eternity that can never go out, and that shines through the veil of time and matter. The saints never say that this light is given to them, but that it is given only to those who have purified their hearts in love for the Lord, on the narrow way which they have freely chosen.
