Ley lines, or dragon lines, are mystical lines that cover the earth in a grid pattern. They are considered mystical, because ley lines have not been proven by science to exist. However, there is still much to learn about the way our universe works.
Ley lines was first used in 1921 by archaeologist Alfred Watkins, referring to supposed alignments of numerous places of geographical and historical interest, such as ancient monuments and megaliths, natural ridge-tops and water-fords.
In 1969, John Michell associated ley lines with theories about alignments of land forms. He believed that a mystical network of ley lines existed across Britain. Since then, ley lines have been used in many theories involving a world energy grid.
Some claim the ability to use dowsing rods to detect ley lines, while others prefer a pendulum or compass. At the center of connecting ley lines, it may be possible to physically sense the energy.
At the points where ley lines intersect, powerful vortices are said to be found. The places that many ley lines meet are often the sites of ancient spiritual monuments, megaliths, and stone circles. Some of these areas, like Sedona, Arizona, are known for their high energy. Others bring stories of UFOs or portals to other dimensions.
