a force shaped in water

I stand on my dune top watching a great wave coursing in from sea, and know that I am watching an illusion, that the distant water has not left its place in ocean to advance upon me, but only a force shaped in water, a bodiless pulse beat, a vibration . . . Somewhere in ocean, perhaps a thousand miles and more from this beach, the pulse beat of earth liberates a vibration, an ocean wave. Is the original force circular, I wonder? and do ocean waves ring out from the creative beat as they do on a quiet surface broken by a stone? Are there, perhaps, ocean circles so great and so intricate that they are unperceived? Once created, the wave or the arc of a wave begins its journey through the sea. Countless vibrations precede it, countless vibrations follow after. It approaches the continent, swings into the coast line, courses ashore, breaks, dissolves, is gone. The innermost waters it last inhabited flow back in marbly foam to become a body to another beat, and to be again flung down. So it goes night and day, and will go till the secret heart of earth strikes out its last slow beat and the last wave dissolves upon the last forsaken shore.
