My musical productions came into existence through understanding and pain. Those which pain has brought forth seem to please the world most ... (out of pain comes new birth ... new life).
The way to do is to be!
Without going outside,
you may know the whole world.
Without looking through the window,
you may see the ways of heaven.
The farther you go, the less you know.
Thus the sage knows without traveling ...
sees without looking ...
works without doing.
