Tao Te Ching

When going one way means life and going the other means death, one-third will be comrades in life, one-third will be comrades in death, and there are those who value life and as a result move into the realm of death, and these also number one-third.

Why is this so? Because they set too much store by life.

I have heard it said that one who excels in safeguarding his own life does not meet with rhinoceros or tiger when traveling on land nor is he touched by weapons when charging into an army.

There is nowhere for the rhinoceros to pitch its horn; there is nowhere for the tiger to place its claws; there is nowhere for the weapon to lodge its blade.

Why is this so? Because for him there is no realm of death.
