I am studying the 6th arcanum in depth and i had a question about where the demon of evil will fits on the tree of life. Does it associated with the vital body or the "causal plane". To me the vital body makes sense because of how the seal of Solomon seperated (with the Tiphereth in the middle) make the inferior and superior triads, with the inferior triad lineing up with the vital, mental and astral. But being the the demon of evil will it seems it would have to do with the body of will, tiphereth, and not the vital.
Do these 3 demons represent the guardians of the thresh hold within or do they symbolize the vital mental and astral lunar bodies, or both.
I know that these have multiple levels of symbols to it, but i need a little guidance. . Any information in relation to this is appreciated. Thank you.
