|The Bovis scale, developed by a French physicist, quantifies or measures how positively or negatively charged a substance is. For living organisms, the key reference point on the scale is found at 6,500 Bovis. From 0 to 6,500 the charge is in the NEGATIVE range, or life-detracting; while above the 6,500 point the energy gradually becomes more POSITIVE, or life-enhancing.The desired minimal energy level for humans is found between 8,000 to 10,000 Bovis, or slightly positive. The Earth itself creates energy in the 7,000 to 18,000 range. This energy is also referred to as "Biophotons", which are light particles invisible to our eyes. This positive energy is necessary to the maintenance on Earth.
