Once you arrive {at a spontaneous awareness of the Great Oneness}, remember: it isn't necessary to struggle to maintain unity with it. All you have to do is participate in it.
LaoziIf you realize that all things change, there is nothing you will try to hold on to. If you are not afraid of dying, there is nothing you cannot achieve
LaoziClay is fashioned into vessels; it is on their empty hollowness that their use depends. Doors and windows are cut out to make a dwelling, and on the empty space within, its use depends. Thus, while the existence of things may be good, it is the non-existence in them that makes them serviceable.
Laozi
