Back in 1994/5, I built and used a "zapper", as described by Hulda Clark. One of the most profound changes I noticed was in my mental attitude to things. Seven minutes into my first zap I was walking around in the twenty-minute lull before the next "session" and I was amazed at how quiet and calm it seemed in my head. I later told several people the feeling was very similar to the one I had when I attested Clear in 1978. (I heard later that remark almost got me declared.)
On other occasions I noticed that my usual resentment at being told off or given orders completely disappeared every time I zapped, and gradually returned over the next week or so.
Since the zapper suppposedly kills bugs (viruses, bacteria, worms etc.) in the body, I simply assumed that some of these bugs had been chomping around in my brain, some effects of which were various attitudes, and killing them removed these added attitudes. I didn't recall Hulda Clark saying much (if anything) about these mental changes, but what I experienced was what I experienced, and I didn't particularly care if anyone else went along with that theory or not. The zapping also fixes my arthritis twinges and other such things, and again, I don't particularly care if someone thinks that is impossible. It works for me.
Today I came across the referenced article, about the exact phenomenon of bugs in the brain hijacking some of the normal neural processes. I smiled.
I still use a zapper every couple of weeks, and have done so since I first started except for the six months I was on the RPF and couldn't.
Your turn Mick.
