I love Chapter Two from the book, 'Tao Te Ching'...
Beauty and mercy are only recognized by people
Because they know the opposite, which is ugly and mean.
If the people think they know goodness
Then all they really know is what evil is like!
Nothing, and Heaven
share the same root -
Difficulty and ease are a part of all work.
The long and the short are in your hands,
Above and below exist because they each do,
What you want and what you say should be the same...
Neither future nor past can exist alone.
The sage has no attachment to anything,
and he therefore does what is right without speaking
by simply being
in the Tao.
