When Zarathustra was thirty years old, he left his home and the lake of
his home, and went into the mountains.  There he enjoyed his spirit and
solitude, and for ten years did not weary of it.  But at last his heart
changed,–and rising one morning with the rosy dawn, he went before the
sun, and spake thus unto it:

Thou great star!  What would be thy happiness if thou hadst not those for
whom thou shinest!

— From Also Sprach Zarathustra by Friedrich Nietzsche (Translated by Thomas Common)
