It don't mean a thing if it ain't got that swing

Rudolf Steiner:  "To see the pendulum swing everywhere in life: that is what matters. For life is not possible unless there is that pendulum swing within it. If you have a clock with a pendulum you can, of course, avoid the swings by stopping the pendulum — but the clock will be of no use to you then; the pendulum must swing if the clock is to tell the time. This is how there must be the pendulum swing in life. Note must be taken of it everywhere."
