Chapter 27, Part 1C - Chuang Tzu

There is that which makes things acceptable, there is that which makes things unacceptable; there is that which makes things so, there is that which makes things not so. What makes them so? Making them so makes them so. What makes them not so? Making them not so makes them not so. What makes them acceptable? Making them acceptable makes them acceptable. What makes them not acceptable? Making them not acceptable makes them not acceptable.

Things all must have that which is so; things all must have that which is acceptable. There is nothing that is not so, nothing that is not acceptable. If there were no goblet words coming forth day after day to harmonize all by the Heavenly Equality, then how could I survive for long?

The ten thousand things all come from the same seed, and with their different forms they give place to one another. Beginning and end are part of a single ring and no one can comprehend its principle. This is called Heaven the Equalizer, which is the same as the Heavenly Equality.
