A man's excellence is like that of water; It benefits all things without striving; It takes to the low places shunned by men. Water is akin to Tao. . . . In all the earth nothing weaker than water, Yet in attacking the hard, nothing superior, Nothing so certain in wearing down strength: There is no way to resist it. Note then: The weak conquer the strong, The yielding outlast the aggressors.
Laozi
