Yün Kiang, rambling to the east, having been borne along on a gentle breeze, suddenly encountered Hung Mung, who was rambling about, slapping his buttocks and hopping like a bird. Amazed at the sight, Yün Kiang stood reverentially, and said to the other, 'Venerable Sir, who are you? and why are you doing this ?' Hung Mung went on slapping his buttocks and hopping like a bird, but replied, 'I am enjoying myself.' Yün Kiang said, 'I wish to ask you a question.' Hung Mung lifted up his head, looked at the stranger, and said, 'Pooh!' Yün Kiang, however, continued, 'The breath of heaven is out of harmony; the breath of earth is bound up; the six elemental influences do not act in concord; the four seasons do not observe their proper times. Now I wish to blend together the essential qualities of those six influences in order to nourish all living things;-- how shall I go about it?' Hung Mung slapped his buttocks, hopped about, and shook his head, saying, 'I do not know; I do not know!'
