Time to run, time to stop

Around 2400 years ago, daoist master Zhuangzi (庄子, 370-301 a.C.) used to tell his disciples this parable:

Once upon a time there was a man that lived allways worried about his own shadow and the footprints he left – he considered them limitations to his freedom. So, he decided to take redeem of them. He began to run, but the footprints would appear so quick as he would put his feet on the floor; the shadow was also always with him, whatever the speed he would run. Then he thought: I should run even faster. And e run faster, faster, till he fall dead.

His mistake, concluded Zhuangzi, was not to understand that, if he would go to a shadowy place, his own shadow would disappear; and if he had stood still, his footprints would not appear again.

So – really there is a time to walk, a time to run, a time do stop and stand still. The science is to know when and where. And it is not so easy, after all.
