All entities move and nothing remains still.
Even sleepers are workers and collaborators on what goes on in the universe.
All things are in a state of flux.
Man, like a light in the night, is kindled and put out.
There is a stability in the Universe because of the orderly and balanced process of change, the same measure coming out as going in, as if reality were a huge fire that inhaled and exhaled equal amounts.
The way up and the way down are one and the same.
