Summary
Analysis
Zarathustra longs for eternity and for the wedding ring “of Recurrence.” He has never wanted to marry or beget children with a woman, unless it’s Eternity, for he loves her. If Zarathustra has ever shattered old law-tables, communed with the gods, laughed uninhibitedly, or lived according to his own will, how should he not lust for Eternity?
Zarathustra sings seven hymns to the Ring of Eternal Recurrence. The hymns are simply a poetic expression of the teaching of Eternal Recurrence, showing how fully Zarathustra embraces life and its recurrence. He can do this because his will to power is uninhibited.
