Observe a river from a distance. It appears to be one smooth, uniform body of water, flowing simply and evenly in one direction.
Now move close to the river, along the shoreline. Walk along and observe the river closely in different spots. In some places you’ll notice eddies in the flow, where the water changes from its primary direction, perhaps flowing sideways, backwards, even in circular motions.
Life is an eddy in the river of entropy.
