Correspondence the Good the Bad and the Ugly

When you decide to work the rituals and the magic/k in this system you will need to do your home work first. Like many of scientist you will need to go through calculations, gathering of tools and instraments, and calculations of work to be done. This is done through Correspondence. But I will tell you something that is important at the end about correspondence.
I will show by example instead of just in what needs to be done before a rite is to be done. So let say you are in need to leave for several days and you feel that you may need some added protection to you home. So you decide to conjure a spirit that you want to protect your home for a time when you are gone for the few days. You decide it to be a spirit that is able to protect. You now look up charts for metal, color, planetary hour, elemental, incence (perfumes that is associated to the said spirit). Then work on substitutions as needed. Then you go to the the grimoire that you are working through such as the key of Solomon the King. Then look up sigils, and glyph associate to the said spirit and needed tools for the operation. Then after gathering the needed stuff and using the correspondence to create needed tools such as a Lamen. Then you will need to calculate the planeary hour. ( will show that in the next article) There is alot more to it but that is it.
So what is Correspondence in the first place? It is items, languages to herbs, roots, planets, stones etc that are associate to each other in a way that are in turn associated to what is needed. Like summoning the protection spirit that is needed to protect your home. You will need to gather needed tools and other associated items to the said spirit or magical work that will in turn make the magical act work. Which is to help in the whole picture.
The thing about correspondence is that it is a good start for a beginning mage to work with. It helps the person who is working with the magic to understand the forces that is being used. As time goes on you will have a better understanding of said forces of energy and you will notice that you will have no need to use correspondnce to needing very little of it use. A true adept will have no need to very little use for it because they will have a understand to how to control and understand these forces of nature.
