Is only actual
In one place
And one time.
When one listens to a barking dog, one might imagine emotion, pain, reaction, anxiety, and self-identification, but actually there is nothing there — just sound from a long and deep corridor, channeled out of nothingness and fading into nothingness again.
Like that dog, we may all strive, but there is truly nothing to be done. If we look deeply into our lives, there is only a thin veneer of self-generated meaning over an immense ocean of nothingness.
What we do only has meaning in the here and now. It will not remain in the next instant. Just do what you can for the present, and leave everything else to happen naturally. Work. Wash. Meditate. Eat. Study. Urinate. Sleep. Exercise. Talk. Listen. Touch. Die each night. Be born again each morning.
