There is no motion in the direction between the poles. Motion is East-west around the north-south axis. North-south is Mind and is Gravity. Gravity power divided, which is called polarisation, is measuring out between mother and father extensions and keeping them equally balanced, and bringing them gradually together again and when they unite as one, polarisation ceases at a zero/center and whatever extends from that zero again is reversed in polarity. There is merely a sequence of balanced extensions from that zero, which is the fulcrum for spiral motion moving around it, the spiral made by the circular motion of those extended gravity points around that centering zero.
