Say, we start off as a moving point of awareness which contains in it the potential for a full breath. Now the breath begins to expand the circle of awareness around the point (i.e. the point sees itself in relationship to all other points in its circle of awareness). Now the point may appear to move relative to the other points in its circle of awareness, but since all motion is relative, the point is actually still. Once this expanding breath has completely released it potential from the point, the circle of awareness is largest, around the point. After this, the contracting breath starts and the circle of awareness is pulled back into the point.
Now this illustration is happening linearly or in TIME. If we go beyond time, then both expansion and contraction are one event.
Expansion implies contraction.
Every expansion generates a proportional potential for contraction.
Contraction implies expansion.
Every contraction generates a proportional potential for expansion.
Expansion and Contraction are one process.
