“Alive, a man is supple, soft; in death, unbending rigor. All creatures, grass and trees, alive are plastic, but are pliant, too, and [in] death all feeble and dry. Unbending rigor is the mate of death, and yielding softness, [the] company of life. Unbending soldiers get no victories, the stiffest tree is readiest for the ax. The strong and mighty belong to the bottom, the soft and yielding rise above them all.
The strongest is he that makes use of his opponent's strength—be the bamboo tree which bends toward the wind; and when the wind ceases, it springs back stronger than before.
— Bruce Lee, Bruce Lee: Artist of Life
