I read this article I found from facebook post it is interesting but seems odd to me from how I work. I would never base the energies of the elements I called in based on the terrain of a particular place. LOL
For me Earth must always come first she is the starting place (the east). She is the basis of all life and to me should always be acknowledged and brought forth first. Followed by water to the South the place of highest energy in the northern hemisphere. When the sun is farthest south is our time of greatest growth. The majority of our body is water and water is the element that represents our emotion. The element of fire is the west, the place where we transmute our emotions when the day is done and learn from them. From the fire the smoke of our transmutation rises to to north the place of the element air where there is no physical form any longer, the place of spirit.
I’m curious about how other people do it?
Many modern practitioners call Elemental energy from each of the directions when they cast a circle. The most widely practiced form of this tradition is to call Air from the East, Fire from the South, Water from the West, and Earth from the North. Many practitioners also add Spirit as a "fifth Element," sometimes calling it "from Within and Without," sometimes calling it from "Above and Below," sometimes asking specific gods and goddesses to join in their right, and sometimes (whew!) simply representing Spirit themselves.
