Your eyes reveal what is inside you. They are the lamps of your body. If they have light within them, then that is a sign that your whole being is filled with light. If your eyes are filled with darkness, then it is proof that your whole being is filled with darkness. Be mindful of the light within you. If your whole being is filled with light, then your spirit will shine forth like a lamp does.
