You've seen the world, and all you've seen is nothing; and everything, as well, that you have said and heard is nothing. You've sprinted everywhere between here and the horizon; it is nothing. And all the possessions you've treasured up at home are nothing.
Omar KhayyamThe Revelations of Devout and Learn'd Who rose before us, and as Prophets burn'd, Are all but Stories, which, awoke from Sleep They told their comrades, and to Sleep return'd.
