The Aura or Halo around Saints...

As one becomes more spiritual in nature, thinking only of the welfare of others and not of power and greed, the higher the molecules of one's being will vibrate. As we know in our dimension, it is possible for these molecules to vibrate so rapidly that the frequency becomes pure light. This is why Saints are called the Forces of Light. They depend on the light from The Source -The Creator, God, for their existence."
