Everything flourishes.
Each return to its root
Returning to the root is called tranquility.
Tranquility is called returning to one’s nature.
Returning to one’s nature is called constancy.

(Tao Teh Ching, Chapter 16)

There is something formless born before Heaven and Earth
So silent! So ethereal!
Independent, changeless, circulating, ceaseless
I do not know its name.
To identify it, I call it “The Tao”
Forced to describe it, I call it “The Great.”
Great means passing.
Passing means receding.
Receding means returning.

(Tao Teh Ching, Chapter 25)
