“Life often goes along in a stream. The details float by like a leaf on a river. The current is pushing and pulling the leaf, but we do not see it because we are standing on the banks of the river. There are moments when the leaf is caught up in little eddies. Events pile up. They gather like twigs--like flotsam and jetsam--caught up in the stream of life. Time blocks and unblocks in little bursts at such places. Information pours through like water. The details crystallize. Various pressures and turbulences in the river, pouring into the sea of life, push and pull, but we do not see it. We do not see the leaf or the pushing and pulling.”
