Everything and anything in your life can be used as an analogy, a metaphor, a teacher.  Let us use music.  Why do you like some songs and not others?  It is a matter of resonance.  When you feel a resonance with the tones, all is well.  You are in harmony.  The opposite is called dissonance.  When your life is not going well, you feel and experience dissonance.  Life is not harmonious.  This is yet another way that Spirit lets you know you are or are not in harmony with the Great Spirit.  To come into resonance, to find your best tune, allow Spirit to dance you, not the other way around.  Then even the lyrics to a song will snag your attention, a beautiful sign from the Universe that yes, Somewhere Over the Rainbow there is a greater reality and you are forever and always part of it.
