The men who are great live with that which is substantial, they do not stay with that which is superficial; they abide with realities, they do not remain with what is showy. The one they discard, the other they hold.
LaoziThe great Tao flows everywhere. All things are born from it, yet it doesn't create them. It pours itself into its work, yet it makes no claim. It nourishes infinite worlds, yet it doesn't hold on to them. Since it is merged with all things and hidden in their hearts, it can be called humble. Since all things vanish into it and it alone endures, it can be called great. It isn't aware of its greatness; thus it is truly great.
Laozi
