Just as you have energy centers in your body called Chakras, so too does Mother Earth.
It is generally agreed that Gaia has seven major chakras distributed evenly across her body and connected to one another via two lines of energy that intersect at various points on the earth. The first chakra is located at Mount Shasta in Northern California; the second is in Lake Titicaca in South America; the third chakra is in Uluru-Kata Tjuta in Australia; the fourth chakra resides in Glastonbury in England; the fifth chakra is at the Great Pyramid in Mount of Olives; the sixth chakra is in Kuh-e Malek Siah in Iran, and the seventh chakra is in Mount Kailas in Tibet. In addition to her seven major chakras, she has minor chakras and other vortexes of energy that are significant to her life-energy system, and all these energy centers need caretaking. Just as we can heal ourselves through our own chakras, we can heal and support Gaia through hers.
While it would be a wonderful experience to visit one of the earth's chakras, you can always participate in loving and healing Gaia wherever you are. Maintaining an awareness of the regions in which her chakras reside can be very powerful. You may place photos of the locales on your altar, sending healing energy to each of her chakras during your meditations. As you consciously connect your energy system to her energy system, the true meaning of groundedness reveals itself--it is a relationship with Gaia in which we acknowledge our calling as the caretakers of her soul.
