What's inside you?

Have you ever noticed how incredibly beautiful the simplest, most ordinary things can become when illuminated with light? I think love works the same way: when we love, or when we know we are loved, there is a glow about us -- and, of course, we've all known how dark the world can feel when we've lost love, or gone too long without feeling its warmth.

It's almost as if light and love are two different ways of expressing the same -- uh-oh.  What is the right noun to use here?  Impulse? Quality? Spirit?  Perhaps I'll let you fill in that blank...

All of which reminds me of a wonderful book title I encountered as a librarian back in the 70's: What's Inside You, It Shines Out of You.  Maybe that's today's question...
