Tao te Ching: 77

Heaven's way is indeed like the bending of a bow.
When (the string) is high, bring it down.
When it is low, raise it up.
When it is excessive, reduce it.
When it is insufficient, supplement it.
The Way of Heaven reduces whatever is excessive and supplements whatever is insufficient.
The way of man is different.
It reduces the insufficient to offer to the excessive.
Who is able to have excess to offer the world?
Only the man of Tao.
Therefore the sage acts, but does not rely on his own ability.
He accomplishes his task, but does not claim credit for it.
He has no desire to display his excess.

The Way of Heaven, known as the Tao, is a path of moderation. Not for the sake of making things indiscriminate, but because all things are ultimately one with the Tao. The Buddhists call this Buddha-nature. Regardless, since all things are one, there is no need to make one area deficient to increase the surplus of another.

This is the way of man. Think about taxes. Accumulation of resources denies those resources to another. You could use the money that goes to taxes for something you need. Something you truly need, not just something you want. And someone else, with a surplus, has money for what they need, what they want, and for taxes. What saves a man from being either the victim or the perpetrator?

Frugality, such as the sage possesses. Chapters 2, 10, and 51 all discuss hsüan-te.
