Everything goes, everything comes back; eternally rolls the wheel of being. Everything dies, everything blossoms again; eternally runs the year of being. Everything breaks, everything is joined anew; eternally the same House of Being is built. Everything parts, everything greets every other thing again; eternally the ring of being remains faithful to itself. In every Now, being begins; round every Here rolls the sphere There. The center is everywhere. Bent is the path of eternity.

J. In the following few days Nietzsche sent short writings—known as the Wahnbriefe ("Madness Letters")—to a number of friends (including Cosima Wagner and Jacob Burckhardt). Now with the new style of Zarathustra his work became even more alienating and the market received it only to the degree required by politeness.

Nietzsche's key ideas include the "death of God" the Übermensch the eternal recurrence the Apollonian and Dionysian dichotomy perspectivism and the will to power. His sister Elisabeth Förster-Nietzsche acted as curator and editor of Nietzsche's manuscripts during his illness. [citation needed].
