Oh, I forgot,
you can use the energy rings also for electric service panels, but you really only need them if you have more than 7 negative Hartmann/Curry lines and the cause is found there. If you find less than 7 you can cure them with the sticks.
These rings are said to deepen meditation as well. But if you have a positive vortex in your home or cured negative ones you can sit there to get these benefits.
