Summary
Analysis
Zarathustra breaks into song, addressing his soul. He sings of his self-overcoming, how he has purged all shame and virtues from his soul and granted it freedom over all things. His soul is now weighed down with wisdom and happiness. His soul longs to give out of its fullness. Until the future “nameless one” arrives and is open to free will, the soul will have to sing its longing.
Because the Superman has not yet come, and because humanity is not yet ready to accept Zarathustra’s teaching, he can only sing of the future, and only to himself.
