The Dao is nonaction, yet nothing is left undone.
Purity of mind does not come from knowledge and wisdom.
What is knowledge? What is purity?
Knowlegde is to give up all wisdom. Purity is to be empty in going along.
Going along, not following: this is pervasion of mind.
Pervade the One and all affairs are done!
The One is the root, affairs are the gate.
When affairs return to the One, the One is always there.
