There is great beauty in "ugliness",
and there is great joy in "pain."
We know each through their opposites.
Existence and non existence give birth to the idea of each other.
The idea of difficulty and ease produce one another.
Length and shortness fashion out the figure of each other.
High and low contrast and measure each other,
like how musical notes become harmonious through
the relation of one with another
and past, present, and future require each other.

This is how the Sage
accomplishes without doing
anything at all and he
and teaches without
having to say a word.
As things arrive and disappear
he lets them come and go freely.
He possesses but does not own
and perform without expectation.
When he finishes his work,
he releases it without attachment,
that's why it continues eternally.
