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.
Be humble and you will remain entire. The sages do not display themselves, therefore they shine. They do not approve themselves, therefore they are noted. They do not praise themselves, therefore they have merit. They do not glory in themselves, therefore they excel.
