At first my english isn't very well too, so I am not sure if I get the original point, but after Crossfire was so nice to link it to a thread near by your theme I will give it a try..
I do not belive in sin nor do I belive in the excuse that others are responsible for what i am doing.
I am I, When I do something wrong it is my fault, not the fault af a Ghost, a God or a Djinn or another Person... I have done it, it was what I have choosed.
The question where our thoughts came from, where we get the abilities off, is another question, where I have to give a deeper look in my beliefs:
Mortal beings have 4 Parts which have to come together for creating a mortal live. The mortal body which is a vessel within the material world, The mortal Ba which is the Energy of life that bind the parts together, the immortal name and the immortal Ka which can be named as soul or higher Self.
Whithin the Ka we save our knowledge, abilities, experience when we are growing within mortal live. After our mortal parts have died, the Ka and the name can go to the Duat, or can choose to came back to Amduat to live a new mortal live.
When the Ka is again bound to a mortal being, there are borders so that the new being can not take an aware access to what is saved into the KA. There are people where the Borders are higher, and others where the borders are lower more permeable.
The nature of the borders are the why we have more or less unaware influence from old informations out of the Ka. They are shown as special abilities, Instinct, intuition.
If the borders are to low there can also be the appearance of forreign words come to your mind. I think that is what you name influence of Djinns. That are not the words of our actual aware mortal existance but from former existance of our Ka.
But Equal if you hear your older selfs or not. It is allways your decision what you are doing.... If you can not stand them look for help.
If your faith has no answers for you to fight back what you can not life with, than go to a doctor, there are Psychopharmaka which are able to build fake borders. They do not stand very long without being renewed with new pills, but they may help.
