Symbolic Circle Casting
The most popular magick circle is a symbolic one, physically cast by walking round the visualized circle area clockwise. It is visible psychically as a circle of light but not seen externally except by those with evolved clairvoyant light — and children.
You can make a symbolic circle before a simple outdoor spell and it is a good way of connecting with the earth energies.
Form the psychic light circle in the air, about waist or knee high, whichever feels more natural, with a pointed crystal or wand held in your power hand (or your index finger). Direct the point at about 45 degrees, casting the circle in front of you so you step into the emerging light and become empowered.
If you wish, you can make a circle-casting chant that you repeat either aloud or in your mind as you walk, for example:
May the circle be cast and so remain unbroken, May the love of the Goddess be forever in our hearts. Blessings Be!
If working in a group, some practitioners like to cast a symbolic clockwise circle straight after the introductory blessing and then welcome other members of the group into it, drawing the psychic circle over head height at the planned entry point (north-west for a north-beginning circle or north-east for an east-initiated one). The guests enter at this psychic gateway and you can then finish off the circle when they have entered.
Personally I prefer to make the circle round the people once they have entered. You can then enter the circle where you began casting it through a visualized doorway, sealing it afterwards.
I think unless it is a real emergency people shouldn’t leave the circle during a ritual as this involves a lot of sealing and unsealing and psychic disturbance.
