It is said that he who has a true hold on life, when he walks on land does not meet tigers or wild buffaloes; In battle he is not touched by weapons of war. Indeed, a buffalo that attacked him would find nothing for its horns to butt, a tiger would find nothing for its claws to tear, a weapon would find no place for its point to enter in. And why? Because such a man has no death-spot in him.

Tao Te Ching, Chapter 50
