Chuck Palahniuk. Ghosts (№ 373)

Maybe the suffering and anguish - this is the meaning of life.
Imagine that the Earth is a big process unit, processing plant.
Imagine a drum for grinding stones:
A rotating cylinder filled with sand and water.
Imagine that your soul - angular shapeless stone that was thrown inside.
A piece of raw material, natural resource: crude oil or mineral ore.
And the pain and the hostility is only burn material that polishes us, rubbing to Shine the souls, purifies them, teaches and develops from reincarnation to reincarnation.
Now imagine that you are on their own, throw in a drum again and again.
It is aware that your assignment on earth is to suffer and suffer.
