mencius said, 'the richest fruit of benevolence is this: the service of one's parents. the richest fruit of righteousness is this: the obeying one's elder brothers. the richest fruit of wisdom is this: the knowing those two things, and not departing from them. the richest fruit of propriety is this: the ordering and adorning those two things. the richest fruit of music is this: the rejoicing in those two things. when they are rejoiced in, they grow. growing, how can they be repressed? when they come to this state that they cannot be repressed, then unconsciously the feet begin to dance and the hands to move.'
