#55 Clarity within, movement without-this produces greatness and abundance. The hexagram pictures a period of advanced civilisation.
It is not given to every mortal to bring about a time of outstanding greatness and abundance. Only a born ruler of men is able to do it, because his will is directed to what is great. Such a time of abundance is usually brief. Therefore a sage might well feel sad in view of the decline that must follow. But such sadness does not befit him. Only a man who is inwardly free of sorrow and care can lead in a time of abundance. He must be like the sun at midday, illuminating and gladdening everything under heaven.
