Love is like a friendship caught on fire. In the beginning a flame very pretty often hot and fierce but still only light and flickering. As love grows older our hearts mature and our love becomes as coals deep-burning and unquenchable.
I think there's a supreme power behind the whole thing an intelligence. Look at all of the instincts of nature both animals and plants the very ingenious ways they survive. If you cut yourself you don't have to think about it.
