Zero
Zero....
This is what everything's about and everything is going towards to....
The main principle that attracts everything. It's the ultimate balance of everything. The returning point that every property above or beyond that is attracted to return back.
Zero is what prevents too much of anything, and it will bias the values to stay in the acceptable range. Almost all the attractive attitudes always sweep and bounce around the balanced point (zero).
It is also the reference point, for improvements, measurements, changes, beginnings and even endings....
