From Friedrich Nietzsche's book, Thus Spoke Zarathustra:
.
"You should first of all learn the art of earthly comfort,
you should learn to laugh, my young friends, if you are at
all determined to remain pessimists: if so, you perhaps,
as laughing ones, eventually send all metaphysical
comfortism to the devil and metaphysics first of all!
Or, to say it in the language of that Dionysian ogre,
called Zarathustra :

"Lift up your hearts, my brethren, high, higher!
And do not forget your legs! Lift up also your legs, you
good dancers and better so if you stand on your
heads!

"This crown of the laughter, this rose-wreath crown
I myself have put on this crown; I myself have
pronounced holy my laughter. No one else have I found
today strong enough for this.

"Zarathustra the dancer, Zarathustra the light one,
who beckons with his wings, one ready for flight,
beckoning unto all birds, ready and heady, a bliss
fully light-spirited one:

"Zarathustra the soothsayer, Zarathustra the sooth-
laughter, not impatient, not absolute, one who
loves leaps and side-leaps : I myself have put on this
crown!

"This crown of the laughter, this rose-wreath crown
to you my brethren do I cast this crown! Laughter
have I pronounced holy: you higher men, learn,
to laugh!"
