If you realize that all things change, there is nothing you will try to hold on to. If you aren't afraid of dying, there is nothing you can't achieve. Trying to control the future is like trying to take the master carpenter's place. When you handle the master carpenter's tools, chances are that you'll cut your hand.
The Tao can't be perceived. Smaller than an electron, it contains uncountable galaxies. If powerful men and women could remain centered in the Tao, all things would be in harmony. The world would become a paradise. All people would be at peace, and the law would be written in their hearts. When you have names and forms, know that they are provisional. When you have institutions, know where their functions should end. Knowing when to stop, you can avoid any danger. All things end in the Tao as rivers flow into the sea.
