The magical circle is another extension of mans desire to dominate. A sorcerer standing in the middle of a circle clearly suggests he is indeed ready to take control and responsibility for his actions. The circle is simply a space where the magician controls his world.
Interestingly, performing rituals without a circle has on many occasion got spirits drawing sexual fluids from me to raise energy as there wasn’t enough without the circle to hold it. I have also had trouble concentrating at times and maintaining awareness, the spirits presence was also weakening in these situations. The circle therefore holds whatever energies are within from leaving, it will NOT however in my experience stop any force or physical aspects from entering!
The circle is usually surrounded by the four elements from which all of life is composed. Their natural positioning is in honour of the supreme power of the universe, which is Lord Sol himself. To explain this, the sun and all other celestial bodies rise in the east, therefore this cardinal point is given to that first stage of manifestation, which is air. At midday when the sun is at its zenith, the world is bright and hot so fire is attributed to the south. At sunset as the world sinks into darkness, the light of day can only be extinguished by water so west is its station. Midpoint between sunset and sunrise, the sun is in the earth thereby donating north as the cardinal point of earth (Fire and earth would of course be switched if the magician was working in the southern hemisphere, where he would also follow a more anticlockwise route of circle set-up).
A circle universally represents ‘eternity’ as it has no beginnings or endings but as a personal symbol I regard it as mentioned above. It isn’t needed at all if that is to your liking as it’s just a tool, a point focus or a symbol to represent however… points of focus allow my mind to connect and open to my intentions so I choose to use it for these reasons as without it, my thoughts can drift which clearly suggests again the circles ability to contain energy.
Our biggest circle is the earth itself which is (in my opinion) the true nature of the magical circle. Our earth, our planet contains our energies very well indeed as without this facility, we would perish but would it stop another force such as aliens breaking that barrier and coming through to us?
