At the center of our being is a point of nothingness, a point or spark which belongs entirely to God. It is in everybody and if we could see it we would see those billions of points of light coming together in the face and blaze of a sun.
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.
