When you live life from your center, you operate from the indwelling spirit outwards into the visible world, like the spokes of a wheel, radiating God's love, wisdom and power. This is what is meant by being in the world but not of it. You remain calm in a crisis. You carry this calmness with you through the ordinary activities of the day, even when things go wrong... Centered in peace, you experience JOY... This is the culmination of growth in being. What you ARE, far more than what you say or do, will be the witness of your faith.
When you turn within you think you see a light. What you think is the light that you see in the inner world is the light that sees, not the light that can be seen. This is a different kind of light, not the kind of light that can be radiated from a source. This is the all-pervading light. Think of yourself as that light, then your aura will burn more brightly.
