"The behavior of the Great De Follows that of Dao and Dao alone. As a thing, Dao is Elusive and intangible. Intangible and elusive, Yet it contains the Image; Elusive and intangible, Yet it contains the thing. Dim and dark, Yet it contains the essence; The essence is real, For it contains the truth. From the present back to antiquity, The name never disappears. Through it I observe the beginning of all things. How do I know how all things began? Because of this."
