All things pass, all things return; eternity turns the wheel of being. All things die, all things blossom again, eternal is the year of being. All things break, all things are joined eternally the house of being built itself the same. All things part, all things welcome each other again; eternally the ring of being abides by itself. In each now, being begins; round each here turns the sphere of there. The center is everywhere. Bent is the path of eternity.
Friedrich Nietzsche, Thus Spoke Zarathustra I
