It (Tao) is eternally without desire. So, it can be called small. All things return to it, although it does not make itself their ruler. So, it can be called great.
The whole world says that my Way is great like nothing else. It is great because it is like nothing else. If it were like everything else, it would long ago have become insignificant.
Heaven and Earth last for ever. Why do Heaven and Earth last for ever? They are unborn, so ever living. The sage stays behind, thus he is ahead. He is detached, thus at one with all. Through selfless action, he attains fulfillment.
The Master's power is like this. He lets all things come and go effortlessly, without desire. He never expects results; thus he is never disappointed. He is never disappointed; thus his spirit never grows old.
