Well, there are a number of things going on here ...
In all fairness to the BKs, you've no evidence to connect him to the BKWSU. Logically, it's impossible for someone to stay awake 24/7 and why on earth would he bother? Can you imagine how boring watching another person's ordinary life for days on end would be? It would be worse than watching Big Brother.
It's not clear how much the external influence is ... and how much is external influences being filtered through your mind and being re-interpreted via your bad BK experience.
How did the BKs treat you?It sounds like to me, it is just a voice inside your head which is referencing all the BK programming you received. It's a jumble of BK influences but not an external BK.
So then the question arises, what to do?
If you believe in spiritualism, psychicism and spirit possession etc, like the BKs, then you have to try and find an 'ethical' spiritual healer ... and, be careful, there are many frauds in this field. Certainly the BKs are not going to help you. It may be doing BKism has opened you up and now you cannot control it. But that does not mean it is a BK doing it. Unlikely I would have thought.
In London, you have the Greater World Christian Spiritualist Association and the Spiritualist Association of Great Britain in Belgrade Square. They may be able to recommend one. A sign of a sincere healer is that don't charge or, say, charge only a minimum which goes to run their church. Many spiritualist churches have free healing sessions. If you have a serious problem, one of their leaders may see you in private.
In unorthodox cases which don't respond to medical treatment, such "healing" can be helpful.
But, on the other hand, hearing voices is also a symptom of medical illnesses and you can discuss that with others who suffering from it, for example ...
Hearing Voices Network Website. They have a big national meeting coming up soon. That way you would feel less alone and strange.
Obviously, their voices would not be BK voices but that is specific to your experiences. They may have Catholic voices, for example.
I would almost guarantee you that the voice you are hearing is not a BK. I can accept there is a voice etc ... there may even be an "influence" ... but I think the voice is just pulling out your BKs experiences and expressing things in BK terms. On one hand it's just not possible for any human being to stay awake 24/7 ... and I am sorry to be so blunt ... on the other, your life and purpose would just not be so interesting or important enough for anyone to want to do so.
Some people say there are no such thing as spirits and what people think are "spirits" are just projections of their own mind and the product of medical imbalances. I don't know. I cannot tell. But what I can say, based on studies in this area, is that the symptoms are reduced and some individuals are benefited *if* they are treated as if they are possessing spirits.
A good spiritual therapist might even find themselves giving the spirit therapy to find out why it is hanging around you.
And, in whatever direction you choose to go in, you've got to decide that you've had enough of it and you want it to stop.
This forum is about the BKs, I'd be interested to hear more of your real world experiences with the BKs ... how they sucked you in, how they spat you out and what they tried to do.
Presumably the BK or "Sindhi" voice only started *after* you met the BKs?
Thank you
