People go on repeating the same thing, again and again. If you look at the faces of people in the world, you will be surprised: why do all these people look so sad? Why do their eyes look as if they have lost all hope? The reason is simple; the reason is repetition. Man is intelligent; repetition creates boredom. Boredom brings a sadness because one knows what is going to happen tomorrow, and the day after tomorrow… until one goes into the grave, it will be the same, the same story.
