"In all of the world nothing is more pliant than water.
And yet it has no equal resiliency against that which is hard.
It cannot be changed by anything.
That which is weak conquers that which is strong;
that which is soft conquers that which is hard,
The entire world knows this,
but no one can act accordingly."
~ Lao Zi, Dao de Jing (Tao Te Ching), verse 78
