The world is deep:—and deeper than e’er the day could read. Not everything may be uttered in presence of day. But day cometh: so let us part!
The heaven blushes and Zarathustra asks if he has said unspeakable things. Day comes, so they must part.
- SolitudeThe two-ness of friend and friend, and the unutterable depth of the world, bid him part from the heaven as day comes.
Nietzsche elsewhere
Nietzsche says that the psychological problem of the type is how one who says and does No to everything hitherto affirmed, bears the heaviest destiny and thinks the most abysmal thoughts, can still be a dancer who finds no objection even to the eternal recurrence of existence but becomes himself 'the tremendous and unlimited saying of Yea and Amen'; this is precisely the idea of Dionysus.
Nietzsche says that Zarathustra speaks to his soul in the dithyramb, of which he is the inventor, citing 'Before Sunrise', and presents 'The Night-Song' as the immortal plaint of one condemned by his superabundance of light and power never to love.
