Qabalah and the Law of One.

[Matt1]

The middle pillar i believe was taught in the inner order of the Golden Dawn, the Rosicrucian order once someone has reached the grade of adeptus minor which corresponds to Tiphareth. The outer order or the Golden Dawn were only taught the banishing ritual of the lesser pentagram. The middle pillar seems to correspond mostly with the idea of Kundalini yoga in the east or sometimes called Kyria Yoga. Interestingly to note too that Regardie in his book Garden of Pomegranates corresponded various psychological terminology as well with the Sephiroth of the tree of life. An example of this would be the trans-personal experience, Crown Chakra and Kether being related. One of the main obstacle i have discovered with the Hermetic Qabalah is getting experiences out of it! Perhaps it was due to being a solitary practitioner rather than being an initiate but i personally found the Qabalah to be a filing system of meta-physical data.
