20.
In no wise ask about the faults of others, for he who reporteth the faults of others will report thine also.
Firdausī.
21.
He that holds fast the golden mean,
And lives contentedly between
The little and the great,
Feels not the wants that pinch the poor,
Nor plagues that haunt the rich man’s door,
Embittering all his state.
Horace.
