The point, which can hardly be repeated too often, is that differentiation is not separation. The head and the feet are different, but not separate, and though man is not connected to the universe by exactly the same physical relation as branch to tree or feet to head, he is nonetheless connected - and by physical relations of fascinating complexity.
The fools standpoint is that all social institutions are games. He sees the whole world as game playing. That's why, when people take their games seriously and take on stern and pious expressions, the fool gets the giggles because he knows that it is all a game.
Life is like music for its own sake. We are living in an eternal now, and when we listen to music we are not listening to the past, we are not listening to the future, we are listening to an expanded present.
For the perfect accomplishment of any art, you must get this feeling of the eternal present into your bones - for it is the secret of proper timing. No rush. No dawdle. Just the sense of flowing with the course of events in the same way that you dance to music, neither trying to outpace it nor lagging behind. Hurrying and delaying are alike ways of trying to resist the present.
Tomorrow and plans for tomorrow can have no significance at all unless you are in full contact with the reality of the present, since it is in the present and only in the present that you live. There is no other reality than present reality, so that, even if one were to live for endless ages, to live for the future would be to miss the point everlastingly.
If, then, my awareness of the past and future makes me less aware of the present, I must begin to wonder whether I am actually living in the real world.
