Some further thoughts on the feedback machine.
I’ve updated the machine with pure copper plates (99.99%) and this feels quite different than the aluminium foil that I’ve used previously. The feeling/sensation is more electrical in nature and travels through the body and stimulates crown chakra and also meridians in the body. I suspect that it follows the natural pathways of pranic energy and releases blockages but will need to get feedback from my friends from the healing group as some of them are very sensitive to feeling and seeing subtle energies.
