Positives travel while linked to the origin of it's Negative.

Open up a rock after logging how it lays in the position of it's formation.
It is forever locked into it's design.
The positive Arch's away from it's connected Negative creating The Magnetic Field of it's extension.
The same thing is applicable to beings that once were and have imprinted their energy in accreted routines seen today as haunting. The difference is, what we call demons are entities and the nemesis of the FIRST POSITIVE. The negative is the equal shadow for a parallel negative entity to sock puppet from their dimension where time never looses it's data. It is then used (buy elitist  who mantra for power at all cost to the Positive Innocent), to manipulate the energy of the subject to infuse with more wherewithal.
