You seem very young and naive. I haven't read all the posts in this thread, but I'll say one thing. There are MANY fine examples of demon
possession, and I don't think you'd like what you see.
Serial killers, random murderers, rapists, etc....of course, this is all based on my own faith and understanding. Some might even attribute rage,
envy, depression, illness/disease, addiction, and all the other "bad" things that plague us in this physical life as being demonic. My
long-standing theory is that demons (one form of them, at least) are none other than parasites, which our culture is not in the habit of purging like
the ancient cultures were. So when you have an entire civilization literally "possessed", then you get one like ours where people are literally
going insane, paranoid, hating each other, depression/suicidal, greedy, and addicted to every thing that can be possibly have an addiction.
It is well known that our bodies are temples that house a spirit (us). When that temple is not clean, then unclean spirits are able to enter and
destroy that temple. This isn't based on any one religion, as this is a sentiment echoed throughout all world religions, and one that would be
wisely heeded.
It is my assertion that most of us are already "possessed" to some extent, if you already experience any of the above things I listed. If you do
experience any of those, does it make you happy? I'd venture to say it does not, and most likely, you're miserable, looking for happiness and
fulfillment in your life. Inviting MORE demons in will not give you that happiness and fulfillment.
If power is what you want, go the other way. You already have it in you, and I have plenty of books that describe supernatural human abilities from
average people all over the world - and the common threads between all of them. Religion doesn't matter, but meditation and learning to harness
one's energy (Chi or Qi), and living in a giving, loving and grateful mode will lead to what eastern philosophies refer to as the Siddhis or Iddhis -
super human powers. If my memory serves me correctly, there are 9 levels of these, which ironically, Jesus' miracles all fell into one of these.
Flying/levitation is one, but the list goes on to even more amazing powers. But the key is - you cannot be self-serving or self-gratifying to achieve
this.
With demonic possession, normal life gives you that, and the more you go down the wrong path, the more you'll be possessed until you end up on death
row one day, or killed in some horrible manor. It's believed that those with "good" souls die gently - the soul leaves the body as gently as a
hair being plucked out of milk. A "bad" soul gets RIPPED from the body, feeling like a spiked chained being pulled out of your mouth from the gut.
I believe this is an eastern belief, but it is not limited to the east, as I recall hearing it in other cultures as well. At any rate, what you're
talking about WILL destroy your life, and your soul could be in jeopardy, INFINITELY, because of your willingness to sell it.
Wouldn't it be the wiser choice to research going down the other path? There's more power there, and the reward is unfathomable!
