Beauty is given birth through ugliness
and good is given birth through evil.
Therefore ‘is’ and ‘is not’ originate from each other.
Difficult and easy become one another,
long and short form one another,
high and low position one another,
sound and silence define one another,
future and past accompany one another.
Therefore the wise person lives without effort in his daily life.
He practices a wordless doctrine.
Good and bad come to him
and he refuses neither.
He assists in developing people
but he does not presume ownership over them.
He works but is not attached to the fruits of his labor
and does not dwell on his accomplishments.
Because he does not take credit for his accomplishments,
they last forever.
-Lao-tzu- (Tao Te Ching, verse 2, interpretation by Robert Brookes)
