生之徒，十有三；死之徒，十有三；人之生，動之死地，十有三。
Of every ten three are ministers of life (to themselves); and three are ministers of death.
There are also three in every ten whose aim is to live, but whose movements tend to the land (or place) of death.
夫何故？以其生，生之厚。
And for what reason?
Because of their excessive endeavours to perpetuate life.
蓋聞善攝生者，陸行不遇兕虎，入軍不被甲兵；兕無所投其角，虎無所措其爪，兵無所容其刃。
But I have heard that he who is skilful in managing the life entrusted to him for a time travels on the land without having to shun rhinoceros or tiger, and enters a host without having to avoid buff coat or sharp weapon.
The rhinoceros finds no place in him into which to thrust its horn, nor the tiger a place in which to fix its claws, nor the weapon a place to admit its point.
夫何故？以其無死地。
And for what reason?
Because there is in him no place of death.
