I wish you peace as I'm sure you also would wish me peace inside too.
Of course I wish you peace, and thanks.
Again. I'm not trying to attack you or your faith by posting any of this.
I think this IFS stuff simplifies what is complicated spiritually but can be helpful, yet if you are trying to channel spirits, they are not the Holy Spiirt either. Its not something to forcus on but if we don't acknowledge it, we are numb and unaware. I'm really sorry what you have been through. I know what its like not to sleep. I acknowledge IFS stuff but I redirect to objective truths in the New Testament.
See, I'm not seeing a connection here. This is psychology, not channeling spirits. Actively choosing to assign a sort-of-personality to a portion of one's mind doesn't involve the supernatural at all, and I really don't see where in the New Testament or Old there is anything to tie these things together.
Let's consider the example of, since I'm drinking coffee right now, a drug addict. Someone suffering addiction could well benefit from saying to themselves 'this addiction is not part of my identity, my core self, my soul; it is something else.' The IFS model would classify this as one of the manager-type subpersonalities. This may make overcoming the addiction easier, and this is true in my experience. Craving comes up and one thinks 'oh. it's that thing again, that internal enemy that works against me.' This makes the craving easier to resist.
Whether it's the well understood psychological and physiological mechanisms of addiction, or something like an ingrained reply to years of abuse, the base idea is the same. Calling the problem area a distinct subpersonality is only an analogy that allows to control subconscious behavior.. it is a useful fiction.
And I am concerned that equating it with channeling spirits may block someone from a useful course of therapy and pain relief.
(edit) since you edited your post, I guess I'm going to drop the subject. I do hope you reconsider this however, it is not incompatible with your faith and can be extremely helpful. Anyway, good luck in dealing with your issues.
