As it acts in the world, the Tao is like the bending of a bow. The top is bent downward; the bottom is bent up. It adjusts excess and deficiency so that there is perfect balance.
Too much polishing and you spoil things. There's a limit to the expressibility of ideas. You have a new thought, an interesting one. Then, as you try to perfect it, it ceases to be new and interesting, and loses the freshness with which it first occurred to you. You're spoiling it.
Everything is already perfect. And if you can accept that everything is already perfect, the imperfection is a part of the perfection. What's to worry about?
And if there be any addition to knowledge, it is rather a new knowledge than a greater knowledge; rather a singularity in a desire of proposing something that was not knownat all beforethananimproving, anadvancing, a multiplying of former inceptions; and by that means, no knowledge comes to be perfect.
