Tao Te Ching – Lao Tzu – chapter 66
"Why is the sea king of a hundred streams?
Because it lies below them.
Therefore it is the king of a hundred streams.
If the sage would guide the people, he must serve with humility.
If he would lead them, he must follow behind.
In this way when the sage rules, the people will not feel oppressed;
When he stands before them, they will not be harmed.
The whole world will support him and will not tire of him.
Because he does not compete,
He does not meet competition."
