Makes sense with the Herxheimer reaction and this actually fits with Eeman's description of many peoples' experience while using the relaxation circuit. They first experienced discomfort, sometimes convulsions & uncontrollable crying, but this would pass (sometimes not until the 3rd or 4th session) and be replaced by a euphoric sense of peace and the feeling that something great has happened in the body. Like it has to get worse before it can get better.

Fantastic you are "in the process of buying the supplies to build a few"

You are a man of action! If indeed you are a man? Not sure if we established that? I assume you are.

Anyway, I couldn't help but get started right away myself and use what I had to create a basic version.

I am using wands of Horus as the holders, described in this post (basically just copper & zinc tubes jammed full of quartz crystals to take advantage of the piezoelectric effect which is activated by the heat of the hands) and I am using spirals over straight lines because Eeman didn't know in the 1920s that Cosmic energy (or whatever you like to call it, Chi, Prana, etc) prefers to travel in spirals over straight lines. This was not discovered till later, I believe by Philip Callahan, who observed the flight paths of moths at night. The idea is well understood now by the electroculture community and we always make our devices (spirals & antenna) to account for the best possible flow of energy. Vines use this technique to attract sufficient energy to their roots.

Replicated with this antenna, which has in the last three months turned this space into something quite spectacular.

The antenna has an insulated copper wire running down it.

And spirals are, as far as I know, the most effective way to channel this type of energy.

With that said, I've not finished reading Eeman's lengthy book in which I hope to find some kind of explanation for the specifics on his rectangular meshes (there are no right angles in nature) as a mechanism for the transfer of this energy.

What I can tell you after doing two 30min sessions today is that I felt my hands getting extremely hot. Hotter than they would normally if I was just gripping the wands. Also there was a faint ringing in my left ear which continued through most of it. I didn't sleep but I felt very rested at the end of each session and have had an extremely energetic day. Even now I still feel awake past midnight, which is very unusual.

Am putting together a post to describe the device and what I have learned so far.

I have been able to find "BIOCIRCUITS: AMAZING NEW TOOLS FOR ENERGY HEALTH" by Leslie & Terry Patten. Perhaps this is a different book to the one you mentioned? Looks very interesting however and I will check through it tomorrow. Perhaps they make some reference to why they would use rectangles over spirals?
