Panta Rhei, everything flows, everything changes, nothing is permanent (Heraclitus, 540-480 BCE). Everything is perishable, life is perishable, my life is perishable. Memento mori.
A rock in the surf, immortalized in art, indestructible ceramics. Forms made permanent by fire. A continuous tradition of millennia in the history of mankind. Everything seems forever.
But appearances deceive, everything flows. Life is flowing, even if we have to say good bye.
Panta Rhei.
