故堅強者死之徒，柔弱者生之徒。
Firmness and strength are the concomitants of death; softness and weakness, the concomitants of life.
是以兵強則不勝，木強則共。
He who relies on the strength of his forces does not conquer; a tree which is strong will fill the out-stretched arms, and thereby invites the feller.
強大處下，柔弱處上。
The place of what is firm and strong is below, and that of what is soft and weak is above.
