For myself as a writer -- and for any artist in the process of creating -- I realize sometimes that I am just an instrument, a channel, a conduit for a spirit far greater than myself.  There's something truthful coming through me . . . . This is the experience of co-creation.  We realize, "My God, we're creating with God and God needs us to create."
