Fill your bowl to the brim and it will spill. Keep sharpening your knife and it will blunt. Chase after money and security and your heart will never unclench. Care about people's approval and you will be their prisoner. Do your work, then step back. The only path to serenity.
Express yourself completely, then keep quiet. Be like the forces of nature: when it blows, there is only wind; when it rains, there is only rain; when the clouds pass, the sun shines through. If you open yourself to the Tao, you are at one with the Tao and you can embody it completely. If you open yourself to insight, you are at one with insight and you can use it completely. If you open yourself to loss, you are at one with loss and you can accept it completely. Open yourself to the Tao, then trust your natural responses; and everything will fall into place.
The wise person dines on something more subtle: He eats the understanding that the named was born from the unnamed, that all being flows from non-being, that the describable world emanates from an indescribable source.
Thus it is that "Some things are increased by being diminished, others are diminished by being increased." What others have taught, I also teach; verily, I will make it the root of my teaching.
