There are many healers who use the energy of crystaline grid of the earth to enhance healing. The terminology is slightly different but I think they are one in the same.http://divinejoy.org/content/planetary-crystalline-grid


I have found you can do this with your feet as well:

Connecting to the Crystalline Grid of Earth

Holding pendulum by the chain ask: "Please connect me with the energy of the Crystalline Grid of Earth". The pendulum usually will start rotating clockwise.

Detox

The Crystalline Grid of Earth has the ability to convert noxious energy into positive and harmonious. You can do a simple body detox by connecting to the CGE (see above) and asking: "Please remove excess toxins and heavy metals from my (or anyone else's) body in a SAFE manner and throw them to the Crystalline Grid of Earth" (I've stressed the safe way of removing toxins as sudden release of toxins can be quite dangerous).

The pendulum will usually start rotating counter-clockwise and once it stops - the session is done.
