O man, take care!
What does the deep midnight declare?
"I was asleep,
From the deep dream I woke and swear.
"The world is deep!
Deeper than day had been aware.
Deep is its woe,
Joy deeper yet than agony.
Woe implores: Go!"
But all joy wants eternity,
Wants deep, deep eternity!"

    - Friedrich Nietzsche - 

from Thus Spoke Zarathustra
