Tao Te Ching Chapter 78
There is nothing weaker than water
But none is superior to it in overcoming the hard,
For which there is no substitute.
That weakness overcomes strength
And gentleness overcomes rigidity,
No one does not know;
No one can put into practice.
Therefore the Sage says:
'Who receives unto himself the calumny of the world
Is the preserver of the state.
Who bears himself the sins of the world
Is king of the world.'
Straight words seem crooked.
