For some years researchers have studied the undeniable influences of electromagnetic fields on living organisms and the research of Dr. Ernst Hartmann, M.D., a well-respected German medical doctor, demonstrates that the geomagnetic field is composed of active and neutral zones, the active areas being lines 21cm wide with the neutral zone lying between the lines. The lines run in a North - South and East - West grid, and are about 2.0m apart on the North - South axis and 2.5m apart on the East - West axis in the temperate zone.

The crossing points of these lines have been proven to cause illnesses if you remain over them for long periods of time such as while in a bed or at a work station. The Hartmann grid can also be affected by man made disturbances such as high tension power lines, highways, cell phone towers and computers.

The effect of a crossing in the Hartmann grid can be amplified by other local characteristics such as an underground stream or a geological fault making that particular spot potentially dangerous. According to Professor Robert Endros, a German physicist, trees growing on the crossing of the grid are prone to being hit by lightning, especially if they are near or over an underground stream. Most trees or plants showing deformities are found on such "knots" of the Hartmann grid.

Geopathic lines are the energetic lines that store and carry negative energy and stress which is harmful to the life force of people, animals and plants and also seem to effect cars, appliances, plumbing, the same lines encountered by dowsers when dowsing for water. There are many reports of people blocking the geopathic stress from their homes and suddenly, appliances that did not work before began working. Others reported that homes that had not sold for three years sold within three weeks of blocking the geopathic stress lines and these kinds of stories are endless.
