Without the Light, the journey of life is fraught with dangers and no traveler's vision can penetrate the haze of self-centeredness. The ímage of God as Light that suffuses all the universe is one that unítes the divine transcendence and immanence... All of creation is replete with "signs" of God's presence, but they cannot be discerned without the Light.
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.
