Yen Yuan asked about perfect virtue. The Master said, 'To subdue one's self and return to propriety, is perfect virtue. If a man can for one day subdue himself and return to propriety, all under heaven will ascribe perfect virtue to him. Is the practice of perfect virtue from a man himself, or is it from others?'
Yen Yuan said, 'I beg to ask the steps of that process.' The Master replied, 'Look not at what is contrary to propriety; listen not to what is contrary to propriety; speak not what is contrary to propriety; make no movement which is contrary to propriety.' Yen Yuan then said, 'Though I am deficient in intelligence and vigour, I will make it my business to practise this lesson.'
