15.

The ancient Masters were profound and subtle.
Their wisdom was unfathomable.
There is no way to describe it;
all we can describe is their appearance.
They were careful
as someone crossing an iced-over stream.
Alert as a warrior in enemy territory.
Courteous as a guest.
Fluid as melting ice.
Shapeable as a block of wood.
Receptive as a valley.
Clear as a glass of water.
Do you have the patience to wait
till your mud settles and the water is clear?
Can you remain unmoving
till the right action arises by itself?
The Master doesn’t seek fulfillment.
Not seeking, not expecting,
she is present, and can welcome all things.

-Lao Tzu, translated by Stephen Mitchell
