Тhe gentle overcomes the rigid.
The slow overcomes the fast.
The weak overcomes the strong."
…
"Everyone knows that the yielding overcomes the stiff,
and the soft overcomes the hard.
Yet no one applies this knowledge.

Simplicity, patience, compassion.
These three are your greatest treasures.
Simple in actions and thoughts, you return to the source of being.
Patient with both friends and enemies,
you accord with the way things are.
Compassionate toward yourself,
you reconcile all beings in the world."
…
"There is no greater misfortune
than underestimating your enemy.
Underestimating your enemy
means thinking that he is evil.
Thus you destroy your three treasures
and become an enemy yourself.
When two great forces oppose each other,
the victory will go
to the one that knows how to yield.

The softest things in the world overcome the hardest things in the world.

In the world there is nothing more submissive and weak than water. Yet for attacking that which is hard and strong nothing can surpass it.

Knowledge is a treasure, but practice is the key to it.

Those who have knowledge, don't predict. Those who predict, don't have knowledge.
