Lao Tse

Some quotes:

Water is fluid, soft, and yielding. But water will wear away rock, which is rigid and cannot yield. As a rule, whatever is fluid, soft, and yielding will overcome whatever is rigid and hard. This is another paradox: what is soft is strong.

We turn clay to make a vessel, but it is on the space where there is nothing that the usefulness of the vessel depends.

A tree that can fill the span of a man's arms grows from a downy tip; A terrace nine stories high rises from level earth; A journey of a thousand miles starts from beneath one's fee.

Respond intelligently even to unintelligent treatment.
