Origin Of Middle Pillar Ritual? Options

[size=7]Hello there, I am new to this board, I am actualy an observant/orthodox jew who has an interest in various off shoots from traditional "kabbalistic" jewish sources. I am simply here to learn/listen/possibly share, not preach or judge anyone. just for the record. now that ive bored you, i am posting here simply because i was wondering if anyone knew of the original source or inventor for the middle pillar ritual? i know it was Israel Regardie who introduced it to the world at large, but was it an invention of his own, or maybe of Crowlies (spelling) organization whom Regardie started his magickal learning with? As for an original traditional jewish source there is to a point a simmilar idea found in the zohar at least in one part about the agrangement of the sefiros but not much in the sense of useing them as basicly western chakras that i have come across. so sorry for the rambiling and please inform me of any information that you might know about its history. Thank you and be well,

Regardie was a student of Crowley. And Crowley was a member of the original Golden Dawn. The Original Golden Dawn was an offshoot of the Rosicrucian's who I think were a mystical offshoot from the Masons.....

Where the Middle Pillar came from out of this I'm not sure, although, the Golden Dawn were the first I hear of using it. Unless the Rosicrucians used it first, which they may have for I have little knowledge of them.
