Gustav Klint (Wien 1862-1918 Wien)

O man! take heed!
What saith deep midnight´s voice indeed
"i slept my sleep,
"from deepest dream i´ve woke and plead
"The world is deep,
"And deeper than the day could read.
"Deep is its woe-,
"Joy- deeper still than grief can be:
"Woe saith: Hence! Go!
"But joys all wants eternity -,
"- Want deep profound eternity!"

Friedrich Nietzche. "Thus Spoke Zarathustra", 1883
