Nothing in the world is more flexible and yielding than water. Yet when it attacks the firm and the strong, none can withstand it, because they have no way to change it. So the flexible overcome the adamant, the yielding overcome the forceful. Everyone knows this, but no one can do it.
LaoziWithout going out-of-doors, one can know all he needs to know. Without even looking out of his window, one can grasp the nature of everything. Without going beyond his own nature, one can achieve ultimate wisdom. Therefore, the intelligent man knows all he needs to know without going away, And sees all he needs to see without looking elsewhere, And does all he needs to do wihout undue exertion.
LaoziTherefore, if a great kingdom humbles itself before a small kingdom, it shall make that small kingdom its prize. And if a small kingdom humbles itself before a great kingdom, it shall win over that great kingdom. Thus the one humbles itself in order to attain, the other attains because it is humble. If the great kingdom has no further desire than to bring men together and to nourish them, the small kingdom will have no further desire than to enter the service of the other. But in order that both may have their desire, the great one must learn humility.
Laozi
