Those who know do not speak;
Those who speak do not know.
Stop up the openings,
Close down the doors,
Rub off the sharp edges.
Unravel all confusion.
Har mo nize the light,
Give up con tention:
This is called finding the unity of life.
When love and hatred can not affect you,
Profit and loss can not touch you,
Praise and blame can not ruf fle you,
You are honored by all the world.
– Lao Tzu
