The person of great virtue has a quality that can come only from the Tao.
The Tao itself is elusive, indistinct.
Indistinct and elusive, within it is form. Vague and intangible, from it comes reality
Profound and mysterious, within it is spirit. This spirit is quite real, from it comes truth.
Since ancient times, the Tao has never departed. By means of it, all things are created. How do I know this is so? Because it is the nature of the Tao.
(from Tao Te Ching, verse 21, translation by Robert Brookes)
