My true love sent to me
Nine drummers drumming,”

“Of the best rulers The people only know that they exist; The next best they love and praise The next they fear; And the next they revile. When they do not command the people’s faith, Some will lose faith in them, And then they resort to oaths! But of the best when their task is accomplished, their work done, The people all remark, “We have done it ourselves.””
—Lao-Tzu (6th century B.C.)
