First gather the herbs that have elements that will attract the desired results for whatever you are creating at the time. We buy only the freshest herbs and have a wonderful supply on hand. Next I suggest a large stone or metal bowl for a safe place to burn the charcoal. It is best to use a mortar and pestal to mix your herbs in. Focus on what you are creating while mixing the herbs.
Preparation is very important for it is the foundation of the spell.
I like to write out my wishes or whatever I am asking for as though they have already happened, I visualize this also as I am writing. When you are finished writing, gather together the candles you wish to burn and be sure to use the proper color for whatever spell you are doing. You can use one or more colors of candles. I put these candles in the center of the alter. You can also put sand in a small metal bowl or rock bowl for burning your charcoal or use a piece of ceramic tile.
