The mother earth is an exact replica of human being; however it does not look like human body; but the energy field around human body i.e. electromagnetic field around a human body (also known as Merkaba or light body), which extends around 50-60 feet in diameter surrounding a human body..
Outside it looks like a perfect sphere as above in picture; but inside it is very complex electromagnetic energy and that energy field is identical to what is around the earth. Science (NASA) has been able to identify this energy field around earth and this energy field moves the same way, the field around our bodies do.
So, there is energy sits around the base of spine of a human body, which resembles like serpent in coiled position, and this energy rises from the spine in different forms. Almost everybody is familiar with sexual orgasm when this energy moves and raises from spine, but not every one is familiar with Kundalini energy, which is same energy, but it moves through different channel and rises up. So, when it moves through different channel, it has different purpose compared to sexual energy, that is used for creation, procreation, and some other deep and bigger levels that we are not aware of. But Kundalini energy rising is to awaken you to "God" or higher level of consciousness and it is said that once you had "kundalini" experience, you cannot stop and you will keep searching for that and in all you life you would want to experience that. For a human body, Kundalini energy moves from the base of the spine through all "Charkra" system and it moves like serpent..
Similarly, mother earth's base chakra that center of the earth where Kundalini energy rises and connects to the surface of the earth in a same serpent like way. In between two points, it forms the "seven charka" system of our earth; however it is temporary and it stays in one location for about 13,000 years and then every 13,000 years, it moves to a different location. Wherever it chooses to move, the people in that area have their "Kundalini" experience in and around 700 miles radius roughly of that area. This energy triggers the kundalini of people living in that area and eventually those people end becoming "Teachers" or "Light" of the world.
This energy has just moved and it is no more where it was. It used to be in the Western mountains in Tibet and this is the reason, we have seen climax of spirituality in Tibet and their teachings for the world. However, it has moved to Andes mountains in Chile, so Peru and Chile would be known as new "Tibet". This movement process started in 1949 and completed in 2008 and the energy also has been shifted from male to female.
Hopefully this description would help; however to understand in great detail, please refer "Serpent of Light" book by Drunvalo Melchizedek...hopefully it
Universe is far stranger that we can ever imagine!
