In the four classical elements, earth is considered the ultimate symbol of the divine feminine. In the spring, at the time of new growth and life, the earth quickens and grows full with the beginnings of each year's crop. The image of Earth as Mother is no coincidence -- for millennia, people have seen the earth as a source of life, a giant womb.
The Hopi peoples of the American Southwest indicated Earth not as a triangle, but as a labyrinth with one opening; this opening was the womb from which all life sprang. In alchemy, the element of earth is represented by the triangle with a crossbar.
The planet itself is a ball of life, and as the Wheel of the Year turns, we can watch all the aspects of life take place in the Earth: birth, life, death, and finally rebirth. The Earth is nurturing and stable, solid and firm, full of endurance and strength. In color correspondences, both green and brown connect to the Earth, for fairly obvious reasons.

Try this simple meditation to help you attune to the element of Earth. To do this meditation, find a place where you can sit quietly, undisturbed, on a day when the sun is shining. Ideally, it should be in a place where you can really connect with everything that Earth represents. Perhaps it's a hillside outside of town, or a shady grove in your local park. Maybe it's somewhere deep in the woods, under a tree, or even your own back yard. Find your spot, and make yourself comfortable while you perform an Earth Meditation.
Some people believe that lines of energy, called ley lines, run through the earth. The idea of ley lines as magical, mystical alignments is a fairly modern one. One school of thought believes that these lines carry positive or negative energy. It is also believed that where two or more lines converge, you have a place of great power and energy. It is believed that many well-known sacred sites, such as Stonehenge, Glastonbury Tor, Sedona and Machu Picchu sit at the convergence of several lines.
In the Tarot, Earth is associated with the suit of Pentacles. It is connected with abundance and fertility, with green forests and rolling fields. Invoke Earth for workings related to material wealth, prosperity, and fertility. This is a symbol to use when connecting with the comforts of home, the blessings of the hearth, and the stability of family life.
