The highest benevolence acts without purpose.
There is no greater danger than underestimating your opponent.
The soft and weak can overcome the hard and strong.
A good mooring needs no knot, still no one can untie it.
Heaven and earth are ruthless, and treat the various creatures as straw dogs; the sage is ruthless, and treats others as straw dogs.
The sage does not hoard. The more he helps others, the more he benefits himself, Having bestowed all he has on others, he has yet more; having given all he has to others, he is richer still.
