Tao Te Ching 8

The highest good resembles water.

Water benefits the whole planet effortlessly
flowing always to the lowest point,
just as cosmic energy [/Tao] is found where there is no pretension –

... forming a pool naturally
... reflecting each heart's depth
... refreshing all who seek
... responding preciely to each environment
... sweeping all before it without distinction
... infinitely flexible
... taking alternative forms in extreme conditions

Seeking no advantage for itself
its force is beyond argument, appeal or reproach.
