Thus an army without flexibility never wins a battle. A tree that is unbending is easily broken.
LaoziNothing on earth is so weak and yielding as water, but for breaking down the firm and strong it has no equal.
LaoziWhen one gives whatever one can without restraint, the barriers of individuality break down. It no longer becomes possible to tell whether it is the student offering himself to the teacher, or the teacher offering herself to the student. One sees only two immaculate beings, reflecting one another like a pair of brilliant mirrors.
Laozi
