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,

Just for the Record Regardie was never a student of Crowley. He worked as his secretary only. Regardie took the job hoping that Crowley would teach him but that never happened.

The rough version of the MP existed for sometime but there is debate if it did in fact come from the orginal Golden Dawn or out of the depths of the Stella Matutina. There seems to be some confusion there. Regardie did come into contact with it for the first time while he was a member of the Stella Matutina and refined the technique a bit and then later made it a popular ritual through his writtings. He was a big believer in the effectiveness of the ritual.
