Beings from within NPMR make contact with beings in PMR for the purpose of influence all the time -- past, present, and surely it will continue in the future. Many, if not most of us, are being nudged and helped along with our lessons from time to time -- what else are "guides" for. In the opposite direction Some PMR residents are also being encouraged to sow the seeds of chaos. In the present we exercise our free will and make our own choices.
Beings from the NPMR part of OS are allowed to interact rather freely with us -- within the rules, of course -- and according to the investment of time and energy they wish to make. We can open or close ourselves to their efforts. Interaction is structured pretty much the same as it is here among PMR beings -- You see, we actually live, exist, and interact in a larger reality all the time -- most PMR residents just aren't aware of it.
