Extraction Magic
One of the points that I try to convey in my course is the difference between a quality that is inherent of a correspondence that magicians use as a tool to do magic. Most things like elements and directions, or planetary hours and days, are IMO a correspondence that magicians use to do magic and not inherently true. For instance I do not think that the west is inherently more watery, of that Thursdays are inherently more Jupitarian than Saturdays.
Just like a scientist might take a cell and use enzymes and alcohol to extract the DNA, magicians use colors, directions, days, and hours to extract the force that we want to address in our magic. Certainly some people believe that these things are inherent, and that their system of hours, days, etc is the correct one. They believe Thursday is more Jupiter than Saturday as sure as the sun is in the sky, and that is fine – I am not really writing this to convince them otherwise. I am writing this because if you don’t think that way, some things can throw you…
Once you start adhering to a system you begin standing in its current, and those things can effect you even if you unknowingly make a mistake. Just because it’s a tool, does not mean that it is all in your head. If you start invoking elements and planets using the Pentagram and Hexagram directions, but you cock up the direction there is every chance that you will get the result of the mistake, rather than the intent.
If a deity does not have a planetary correspondence or direction, there is no NEED to assign one. Use the name and symbols and history. No need to limit yourself. You CAN assign one, but be careful. In the process of seeking to find a special time or direction, you might be limiting yourself in other ways.
