Adopt an attitude of simplicity. Serve where it is needed. In so doing, you do not deprive yourself nor compromise your dignity. Abandon mindless consumption in favor of a judicious application of your faculties toward your own nourishment and care for others. Give attention to what is important.
A high-minded self-awareness and a consistent seriousness with no forfeit of dignity are necessary if a man wants to be of service to others. He who throws himself away in order to do the bidding of a superior diminishes his own position without thereby giving lasting benefit to the other. This is wrong. To render true service of lasting value to another, one must serve him without relinquishing oneself.
In bestowing care and nourishment, it is important that the right people should be taken care of and that we should attend to our own nourishment in the right way. If we wish to know what anyone is like, we have only to observe on whom he bestows his care and what sides of his own nature he cultivates and nourishes. Nature nourishes all creatures. The great man fosters and takes care of superior men, in order to take care of all men through them. Mencius says about this:
If we wish to know whether anyone is superior or not, we need only observe what part of his being he regards as especially important. The body has superior and inferior, important and unimportant parts. We must not injure important parts for the sake of the unimportant, nor must we injure the superior parts for the sake of the inferior. He who cultivates the inferior parts of his nature is an inferior man. He who cultivates the superior parts of his nature is a superior man.
