I would like to chime in on this one.
I think in theory, all you need is very little to make your circle. I did my first evocation with the advice of my friend Zoe here…telling me to make it out of salt and use a black cloth for my alter. IT Worked!!
In the days and weeks since I’ve gradually changed my circle and triangle from being that of salt to being made out of colorful rocks, with candles making an outer circle. I also added to my alter with representations of the four elements, and personalized each one. I’ve been opening with LBRP and LBH. Why? Because it works. Setting up a slightly elaborate operation takes time, and in that time I allow my mind to focus on the work ahead. It’s almost a form of meditation in and of itself.
I have no doubt that what I’m using are mere props and decorations. The rock on my alter is just a fucking rock. But, if it helps me visualize and connect with the elemental energy of earth, why not keep it? I know that it may not always be possible to have an elaborate set up, and have no problem with the concept of stripping it down to nothing. It is the Sorcerer who’s standing at the center of the universe and commanding spirits to appear. Everything else is a prop to help you realize your power to do just that!
