It is by his activities and not by enjoyment that man feels he is alive. In idleness we not only feel that life is fleeting, but we also feel lifeless.
The lifetime of a human being is measured by decades, the lifetime of the Sun is a hundred million times longer. Compared to a star, we are like mayflies, fleeting ephemeral creatures who live out their lives in the course of a single day.
Time itself flows on with constant motion, just like a river: for no more than a river can the fleeting hour stand still. As wave is driven on by wave, and, itself pursued, pursues the one before, so the moments of time at once flee and follow, and are ever new.
