Tao Te Ching · Ch. 50

出生入死。生之徒,十有三;死之徒,十有三;人之生,動之於死地,亦十有三。夫何故?以其生生之厚。蓋聞善攝生者,陸行不遇兕虎,入軍不被甲兵;兕無所投其角,虎無所用其爪,兵無所容其刃。夫何故?以其無死地。

Chū shēng rù sǐ. Shēng zhī tú, shí yǒu sān; Sǐ zhī tú, shí yǒu sān; Rén zhī shēng, dòng zhī yú sǐ dì, yì shí yǒu sān. Fú hé gù? Yǐ qí shēng shēng zhī hòu. Gài wén shàn shè shēng zhě, lù xíng bù yù sì hǔ, rù jūn bù bèi jiǎ bīng; Sì wú suǒ tóu qí jiǎo, hǔ wú suǒ yòng qí zhǎo, bīng wú suǒ róng qí rèn. Fú hé gù? Yǐ qí wú sǐ dì.

Going out is life; coming in is death. Three in ten are followers of life; three in ten are followers of death; and three in ten who value life are also moving toward death. Why? Because they cling too intensely to living. I have heard that one who truly knows how to sustain life walks the land without encountering rhinoceros or tiger, enters battle without being struck by weapons — the rhinoceros finds no place to thrust its horn, the tiger finds no place to use its claws, the soldier finds no place to drive the blade. Why? Because such a person has no place for death to enter.
