Verse 15

The masters of this ancient path 
    are mysterious and profound 
Their inner state baffles all inquiry 
Their depths go beyond all knowing 
Thus, despite every effort, 
    we can only tell of their outer signs— 
Deliberate, as if treading over the stones of a winter brook 
Watchful, as if meeting danger on all sides 
Reverent, as if receiving an honoured guest 
Selfless, like a melting block of ice 
Pure, like an uncarved block of wood 
Accepting, like an open valley 
    
Through the course of Nature 
    muddy water becomes clear 
Through the unfolding of life 
    man reaches perfection 
Through sustained activity 
    that supreme rest is naturally found 
    
Those who have Tao want nothing else 
Though seemingly empty 
    they are ever full 
Though seemingly old 
    they are beyond the reach of birth and death
