The ceremonies and rites set out here are not meant to be inflexible. There is nothing stopping you from changing some of all of the ceremonies as you see fit.
You may even dispense with the rites altogether if you wish. For several years Mary and I celebrated the Sabbats by simply being with friends or relatives and enjoying ourselves.
The props and items used and the words recited do not cause anything to happen. They simply focus the Will on the desired outcome. That is all Magick is.
Alister Crowley said, “Magick is the Art and Science of causing Change to occur in conformity with Will.” This means that it is affecting this reality with your mind’s willpower. The rituals are only used to keep your concentration on the job at hand.
Thus, all you need is your thoughts when doing Magick.
The celebrations are exactly that. As long as you enjoy what you are doing on the days of the Sabbats and Esbats, then you are honoring the Lord and Lady.
