Self-luminous, that is what you are.  Your light does not come from outside of you.  It shines from within.  You are this Light … a shining ray of the one Light of Consciousness.  Yes, these are words describing metaphorically your true nature, but this is a light that never goes out … not in you and not in those you love who have left the body.  Can you divide light?  No.  It can be hidden, but not separated.  It must have something upon which or through which to shine to be seen, and here you are, beautiful star.  Focus on the connections instead of the seeming divisions and know you are so very loved.
