'Would you not throw yourself down and gnash your teeth and curse the demon whospoke thus? Or have you once experienced a tremendous moment when you would haveanswered him, 'You are a god and never have I heard anything more divine.' ...The question in each and every thing, 'Do you desire this once more and innumerabletimes more?' would lie upon your actions as the greatest weight.”

“The greatest weight.-- What, if some day or night a demon were to steal after you into your loneliest loneliness and say to you: "This life as you now live it and have lived it, you will have to live once more and innumerable times more; and there will be nothing new in it, but every pain and every joy and every thought and sigh and everything unutterably small or great in your life will have to return to you, all in the same succession and sequence - even this spider and this moonlight between the trees, and even this moment and I myself.

The eternal hourglass of existence is turned over again and again—and you with it, speck of dust!’ Would you not throw yourself down and gnash your teeth and curse the demon who spoke thus? Or have you once experienced a tremendous moment when you would have answered him: ‘You are a god, and never have I heard anything more divine!’ If this thought were to gain possession of you, it would change you as you are, or perhaps crush you. The question in each and every thing, “do you want this once more and innumerable times more?” would lie upon your actions as the greatest weight. Or how well disposed would you have to become to yourself and to life to crave nothing more fervently than this ultimate eternal confirmation and seal?”

“Every acquisition, every step forward in knowledge is the result of courage, of severity toward oneself, of cleanliness with respect to oneself.”
