Nothing is weaker than water,But when it attacks something hardOr resistant, then nothing withstands it,And nothing will alter its way.
The above passages from the Tao Te Ching illustrate to us the nature of water: Water is so fine that it is impossible to grasp a handful of it; strike it, yet it does not suffer hurt; stab it, and it is not wounded; sever it, yet it is not divided. It has no shape of its own but molds itself to the receptacle that contains it. When heated to the state of steam it is invisible but has enough power to split the earth itself. When frozen it crystallizes into a mighty rock. First it is turbulent like Niagara Falls, and then calm like a still pond, fearful like a torrent, and refreshing like a spring on a hot summer’s day. So is the principle of wu wei.
