When man creates a disturbance in nature, it protects itself with pathogenic radiations and their emission. Characteristic examples are nodes named after MD Ernst Hartmann, a German doctor from Eberbach, who significantly treated and proved malignancy. Those nodes are where the Earth's magnetic lines intersect. They in a certain regular arrangement form the Global Grid that emits the Earth's magnetic energy.
A person with inadequate buildings, the concentration of a large number of electrical and electronic appliances and devices in the living space, can cause the matching of that node with other sources of pathogenic energy and the node becomes malignant. In more than 20,000 experiments, Dr. Hartman proved malignancy in the combination - Hartman's node + underground water + technical radiation, and his rule was recognized at medical symposia. That rule roughly reads as follows: The place where a person sick with cancer slept is the most harmful geopathological point, where no one should sit or sleep for a long time. If that place is not neutralized, after a few years it will surely be the cause of cancerous conditions again. The ancient Chinese had very good knowledge of the geopathogenic points of the telluric nodes, which today are called Hartmann's nodes, they figuratively called them "demon's door", because they knew that their devitalizing and pathogenic action can be compared to a demon, which maliciously activates to confuse the fate of people, who do not notice anything.

1247. In 2008, the French Institute for Dowsing published Dr. Pere's book "Cosmic Tellurian Radiations" - Pere's rays, their planetary topography, their relationship to people, animals, plants, and especially to cancer. If we look at the globe and sketch, the grid of lines imagined by geographers to facilitate the determination of location, latitude and longitude, and if we replace this perfectly ideal grid with vibrating telluric currents we get "Pere's Grid". Dr. Pere, as an exclusive dowser, in contrast to numerous experiments on land and sea, could state that the Earth's globe is in danger of cosmic-telluric radiation both in the sense of north - south and in the sense of east - west. The term "Peret's grid" means not only a grid on the surface of the Earth, but also a regular three-dimensional "partitioning" of the atmosphere as if there are "invisible walls" on the Earth.
On the occasion of the discovery of "Peret's net", A. de Belizal wrote: "The deductions of Henri Mazzei and Dr. Larvarone, together with the experiments of Dr. Perry, made it possible to determine much more closely the nature of electric and magnetic rays." These rays are not harmful in themselves, but at certain points where they intersect, they fill a certain field on Earth, which is harmful. It is extremely important to deal with this, since this beam is very powerful and at the same time very dangerous, considering the vibrational frequency that is imposed on the cells in the body through modulation. Later, through the studies of many researchers, especially Dr. Ernest Hartmann, one of the founders of the new scientific discipline - geobiology, it was discovered that the Earth's grid contains a much more precise drawing than the drawing of Peré's rays, and that is why it was called "Hartmann's grid" - a geomagnetic grid of force lines that vertically emerge from the ground. Hartmann's network represents an advance in cosmic-telluric radiations. The engineer and dowser R. de Laforet gave a precise description of Pere's rays: All in all, death vibrates - with frequencies and intensities, like some pathetic symphony or some radio broadcast. Isn't that tragic! Hartmann's network consists of magnetic meridians that extend in the north-south direction and magnetic comparators in the east-west direction. The meridians are 2.5 m apart, and the parallels are 2 m apart. Their thickness is from 21 to 25 cm. They form invisible walls that rise vertically and pass through all physical obstacles (land and buildings), because they consist of energy, not matter. The telluric lines of the Hartmann network intersect and determine nodes that represent geopathogenic points and are called Hartmann nodes. They are pathogenic because a harmful wave rises along the vertical lines of these geo-points, which is as aggressive as it is persistent. Sensitive people began to take care of it, feeling certain changes whose cause is unknown. Thus, means of protection were gradually found. It used to be straw, mud houses and other natural materials, where special attention is paid to the selection of the location for construction. Due to exposure to radiation, the consequences only increase over the years. Water flows and energy nodes at the place of the bed sooner or later lead to illness, the body weakens, becomes sensitive to various diseases, and cancerous diseases can also occur. Such places can be determined by dowsing measurements.
