反者道之动，弱者道之用。天下万物生于有，有生于无。
Turning back is how the way moves;
Weakness is the means the way employs.
The myriad creatures in the world are born from
Something, and Something from Nothing.
In Tao the only motion is returning;
The only useful quality, weakness.
For though all creatures under heaven are the products of Being,
Being itself is the product of Not-being.
The movement of the Dao By contraries proceeds; And weakness marks the course Of Dao's mighty deeds.
All things under heaven sprang from It as existing (and named); that existence sprang from It as non- existent (and not named).
