Earthing, also known as grounding, may be a new concept to many of us, but ancient civilizations were well aware of the healing power of mother Earth, which was why they built pyramids and important temples on ley lines. Ley lines are channels of energy that act like highways to transport energy throughout the Earth. They work similar to meridians or energy pathways. The environment of Earth is not only made of soil, water, minerals and rocks. It also contains many complex energy systems, including but not limited to ley lines and energy vortexes. NASA has recently admitted that Earth does have some of these complex energy systems.
