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.
People in their handlings of affairs often fail when they are about to succeed. If one remains as careful at the end as he was at the beginning, there will be no failure.
There is a big misunderstanding about the idea of naturalness. Most people who come to us believing in some freedom or naturalness, but their understanding is what we call [heretical naturalness] ... a kind of "let-alone policy" or sloppiness... For a plant or stone to be natural is no problem. But for us there is some problem, indeed a big problem. To be natural is something we must work on.
Seal the openings, shut the doors, and until your last day you will not be exhausted. Widen the openings, interfere, and until your last day you will not be safe.
