Sometime ideas, like men, jump up and say ‘hello’. They introduce themselves, these ideas, with words. Are they words? These ideas speak so strangely.

Then the day when the sadness comes — then we ask: “Will this sadness which makes me cry — will this sadness that makes me cry my heart out — will it ever end?” The answer, of course, is yes. One day the sadness will end.
