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.
LaoziBe Content with what you have; rejoice in the way things are. When you realize there is nothing lacking, the whole world belongs to you.
Laozi
