Satan is much more than your mind and a part of you and you are much more than a physical person. The physical world is such a small part of reality really -- think of it sort of as a hard crust on the outside of reality. You have been given a hardened flesh suit to get you through this voyage that is suited for travel through this world. Eventually though, the seals give up and you have to eject. =)
Christians tend to identify with their corpse and believe Jesus or God is coming for them, and nothing ever does or will. They lie with their bodies in graves because they think this imaginary Jesus character will find them there and redeem them. Their appearance rots with their bones and look truly fetid and zombieish after awhile -- it's truly saddening... The first time I had seen one I cried nearly one hour I never felt so incensed about someone being lied to in such a drastic way in my entire life. Generally, they seem to hang out for hundreds of years until they cannot find their own location any more and their body is nothing but dust. Much worse however, is if they don't believe in anything at all really -- the skeptic believes they blip out of existence once they pass on. They become mindless blobs trapped in a mental dark prison seeing as there is no afterlife in their view. They truly have the most frightening fate as far as I am concerned; to merely be trapped in an experience-less void for eternity is a daunting prospect to anyone. Thoughts are a reality in the next life, and that which you have patterned yourself to believe can be a cage forever.
I had only learned recently that Japanese culture will retrieve bodies no matter what the expense or effort since they seem to know about this "person haunting their corpse" aspect. It does lend me a little appreciation of their spirituality having been verified by some of my experiences. Sorry to go off track... Some very heartfelt experiences of mine govern these words. Imagine losing a father, mother, or brother and them being left in this sickening state. Therein lies some of my emotional fuel with this issue the Christian lies have a much larger impact than in this life. In the next life your thoughts can become a real binding prison as they are manifest reality in the other place.
To give you a rough estimate of how much larger these "finer" layers of existence are one thing you will notice immediately is the time distortion. Time is related to space in nearly all instances -- basically five minutes in this other realm is like one hour here. A year of our time is a mere thirty days of that places time. This is why when you dream even though you may be sleeping five or six hours -- it seems like you really have spent little over one hour away. Thus, my rough guess or estimate is that this "space" is five times larger than the physical. Some call this an "astral" plane... but like your connection to Satan it is rather coexistent in nature it's not really a different place. I guess a concept of a plane works for understanding.. but, it's more like an onion layer than other location.
I've rambled enough I suppose, but I haven't said anything one cannot experience for themselves. I am just an average man with an atypical thirst for knowledge. Anyone can do the work if they so desire and discover for themselves the truth of it if it is in their nature to pursue such an inquiry.
Nature cannot be "unbalanced" of course. Satan is much more than the processes but rather the reason they even occur. Eventually, theoretically these misled folks will come around but it may take a literal eternity of our time. Thus, in many ways I feel Satan to be too nebulous for most mortal minds. It's easy to mistake the effects, machinery, and the like for the manifestation which directly at least.. really isn't observable.
