Well, it’s one of the greater secrets of Vodoun, to the point where E.A. talks about this, but states he was forbidden despite making numerous please to Baron De Prince that the cults of the Spider and the Green Butterfly actually let him print this material. (The associations of Vodoun Spirits on the Tree of Life/Tree of Death, and the placement of the spheres in relation to parts of the body).
Also, before you go on talking about mixing systems, I’d like you to know that any system you see out there is probably already mixed and not in it’s primary form. Vodoun in itself is a mixture of catholicism, various tribal forms of African Magick, and French Occultism. Each time the system was blended properly, the magick became much more powerful. However, this was done by many skilled magicians.
If you’d studied Babylonian sorcery, you might understand that the Qabalah is not strictly in it’s original form, and that it has been perverted and somewhat altered by the Judeo/Christian world view, and the spirits they assign these points have very Hebrew sounding names. So your statement about it being Jewish Mysticism is not 100% accurate. The Jews lived in Babylon, and just like most culture and religion they have, they took this system of mysticism from the host society they lived in, altered it and called it theirs. Sometimes they were a little more obvious and didn’t alter it much at all before calling it theirs.
The point E.A. was trying to make in his book is that the macrocosm/microcosm relationship of this Quabalah system equates not just to our solar system, but it’s real prize in understanding is these spheres exist on the front and backside of the body and their respective locations on the body. This knowledge is really only useful once you know the association with the correct spirits in the context of Vodoun, and use it to channel them through these spheres. I’m sure it may have other uses, but I am no expert like E.A.
He might have to tell you more about what kind of things “could be done” with this. Despite being unable to publish prior data on the spirits, I think he might have some input in this department.
Best of Luck,
