One of the most basic parts of Wiccan and Neo-Pagan ritual is casting a circle. We cast circles before spells and rituals when indoors (and sometimes outdoors, if need be) to divine the energies between negative and positive, keeping anything that might interfere with our rites out. The word circle is deceiving because it’s more like a sphere that circles you, in the air, through the earth.
I’d like to post a link to a video for this, for the sake of learning circle casting and also for finding a great resource. I’m not alone when I say that TipToeChick has had a positive influence on me. She has a huge following on YouTube, and with good reason. Check her out, and I hope you find the same inspiration that I always have.
