Verse 19

Abandon holiness
Discard cleverness
    and the people will benefit a hundredfold
Abandon the rules of "kindness"
Discard "righteous" actions
    and the people will return
    to their own natural affections
Abandon book learning
Discard the rules of behaviour
    and the people will have no worries
Abandon plots and schemes
Discard profit-seeking
    and the people will not become thieves

These lessons are mere elaborations
The essence of my teachings is this:
    See with original purity
    Embrace with original simplicity
    Reduce what you have
    Decrease what you want
