It seems that RV is a primitive function located in the brain stem. Impressions of distant places or events are received as images. Our beliefs skew our experience so that our experience will seem to support our beliefs. Part of the art of remote viewing consists of learning how to compensate for those filters so the first impression can be held lightly in a kind of freeze frame and clearly seen. It's like listening around the corners of your mind for quanta that come from all directions.
Communication is a function of the intention both to send and to receive.
Everyone, everything, is radiating information always, and all we have to do to receive it is learn how to pay attention. Listening closely is a learned skill. We have all had the experience of someone trying hard not to hear us. We know what we have to do to get their attention. We raise the level of our intentionality and penetrate their defenses.
