The earth carries magnetic and electrical fields and lines that travel in different directions depending on an area’s relation to the north and south poles. The movement of water, the position of the sun and the moon and ‘man-made’ electrical power stations all affect this natural electromagnetic status.
The human body is known to have electromagnetic energy travelling through its system from both an orthodox point of view as well as that of Eastern philosophies, which conclude that all health is created through these meridians or channels.
The subject of geopathic stress is enormous and is poorly documented, although there is much evidence of disease and illness being created through interfering with these lines.
