Ben Zoma said, Who is wise? He that learns from every man; … Who is mighty? He that subdues his nature; … Who is rich? He that is contented with his lot; …
'Now that which is that subtile essence (the root of all), in it all that exists has its self. It is the True. It is the Self, and thou, O Svetaketu, art it.'
When the Tao prevails in the world, they send back their swift horses to (draw) the dung-carts. When the Tao is disregarded in the world, the war-horses breed in the border lands. There is no guilt greater than to sanction ambition; no calamity greater than to be discontented with one's lot; no fault greater than the wish to be getting. Therefore the sufficiency of contentment is an enduring and unchanging sufficiency.
