There are many things worth telling that are not quite narrative. And eternity itself possesses no beginning, middle or end. Fossils, arrowheads, castle ruins, empty crosses: from the Parthenon to the Bo Tree to a grown man's or woman's old stuffed bear, what moves us about many objects is not what remains but what has vanished. There comes a time, thanks to rivers, when a few beautiful old teeth are all that remain of the two-hundred-foot spires of life we call trees. There comes a river, whose current is time, that does a similar sculpting in the mind.
