The nature of the Tao

The Tao is empty and formless, yet its power never runs out. How deep it is—like the source of all things. It blunts sharp edges, untangles disputes, softens bright glare, and blends with the dust of the world. How hidden it is—it seems to exist, and yet it seems not to. I do not know where it comes from. It seems to have existed before the Lord of Heaven.
