"Heaven and earth are long lasting (chiu). The reason why heaven and earth are long lasting: Because they do not live for self (pu tzu sheng). Therefore they last long. Thus the sage puts his body (shen) behind, Yet his body is in front. He regards his body as external, Yet his body remains in existence (ts'un). Is it not because he is selfless (wu szu), That he can fulfill himself (ch'eng ch'i szu)."
