Legge
14 'This is the passion-nature:-- It is the mate and assistant of righteousness and reason. Without it, man is in a state of starvation.
15 'It is produced by the accumulation of righteous deeds; it is not to be obtained by incidental acts of righteousness. If the mind does not feel complacency in the conduct, the nature becomes starved. I therefore said, "Kâo has never understood righteousness, because he makes it something external."
