The whole history of the world, you just study, is a history of sense gratification. Just take, for example, some twenty years ago one Mr. Adolf Hitler came in the scene, and there was great upheaval as war in Europe and America. From 1933 to 1947 or something like that, the whole world was in trouble. But he is gone, finished. And what did he do? Sense gratification, that's all. He wanted that this way government should be, according to his own sense. Another person, just like Mr. Churchill or your President Roosevelt, they said "No. The sense gratification should not be like that. The sense gratification should be like this." [laughter] So it is the war of sense gratification, that's all. One leader is presenting a program of sense gratification, another leader is presenting another program of sense gratification, and there is clash. This is going on. This is the history of the world.
