I would love to see that study. I would imagine they did not use the proper technique, for one. For two, engrams have to be fairly substantial, in order to be so much as noticed by the subject. Recalling a pinch, isn't going to do much. It's not a substantial amount of pain.
Here's how I see a proper study being done.
1. Choose subjects who have noticeably high degrees of mis-emotion. Manic, depressed or both.
2. Have them think about those subjects or incidents, and ask them to let you know when their emotions are about at their peak.
3. At this point, ask them if there are any physical sensations that they can locate and identify.
4. If so, ask them if they can allow it to intensify, and let you know if it does.
5. Also tell them to allow whatever thoughts come into mind, and if it has an impact on the sensation.
Now, when I was about 8, I had a bicycle accident and my chin was split open and required stitches. The doctor, stuck a needle right smack into the area, with a local anesthetic. And it took three or four. Believe me when I say, it as very painful.
That incident, in part, was what I was going through the other day, when I wrote this post. It has come up before in recalls, but I've never been able to get in there, to any great extent. The area had pain shut off, as far as recall, and refused to give up any physiological data.
Until tonite when the chin area is experiencing muscular throbbing and twitching, and a slight tweak of pain. After all these years, it's finally "remembering".
Now, I don't know what an auditor could ever have done to accelerate the process. Not a word was spoken, the entire time. The body, just wasn't going to talk about it, other than keep trying to discharge it through the cranium.
Well, that's the best I can do to describe it, for the moment. I do have numerous incidents were the cranium was used as the point of origin of pain, and clash with the above incident, or something.
The key, it seems to me, is to be able to get the somatic talking and expressing it's self. Once it's done that, fully and completely, there's nothing left. Any other "data", is purely incidental. The force of an engram, relies entirely upon the force of physiological sensation.
