One who can fully develop his nature can also develop the nature of other people and things. He who can fulfill his destiny can also fulfill the destiny of other people and things (1), for the nature of all men and things follows the Way and the destiny of all men and things is decreed by Heaven. I form the substance of all thing without overlooking any, and all things form my substance, and I know that they do not overlook anything. Only when one fulfills his destiny can he bring himself and things into completion without violating their principle.
