Casting The Circle Of Three, Witchcraft And Wicca. When you cast the circle you place a sphere of protection, power and positive energy between the two realms and around yourself that binds and protects you from negative energies and entities that could bring you pain and harm. It's a place of sanctuary from which you call forth the four Guardian Spirits to guide and assist you and call forth your parents, the Moon Goddess and the Sun God to witness your offerings on to them and the place from which you cast out all your energies. Remember you should always give blessings and thanks before closing the circle. Things you will need: Your first athame. Your bell. Witches Circle of Brew. An Exploration of Dark Paganism.
