honest people use no rhetoric;

rhetoric is not honesty.

enlightened people are not cultured;

culture is not enlightenment.

content people are not rich;

riches are not contentment.

so the sage does not serve himself;

the more he does for others, the more he is satisfied;

the more he gives, the more he receives.

nature flourishes at the expense of no one;

so the sage benefits all men and contends with none.
