Those who know don't talk. Those who talk don't know. Close your mouth, block off your senses, blunt your sharpness, untie your knots, soften your glare, settle your dust. This is the primal identity. Be like the Tao. It can't be approached or withdrawn from, benefited or harmed, honored or brought into disgrace. It gives itself up continually. That is why it endures.
LaoziThere is something obscure which is complete before heaven and earth arose; tranquil, quiet, standing alone without change, moving without peril. It could be the mother of everything. Not knowing its name, I call it Tao.
Laozi
