A successful song comes to sing itself inside the listener. It is cellular and seismic, a wave coalescing in the mind and in the flesh. There is a message outside and a message inside, and those messages are the same, like the pat and thud of two heartbeats, one within you, one surrounding. The message of the lullaby is that it's okay to dim the eyes for a time, to lose sight of yourself as you sleep and as you grow: if you drift, it says, you'll drift ashore: if you fall, you will fall into place
