Thelemic or pagan alternative of the Middle Pillar
While it might not be exactly what you're looking for, there's an interesting article about the Middle Pillar exercise as practiced or at least encouraged by the "traditional witch" Robert Cochrane: https://www.patheos.com/blogs/bythepalemoonlight/2018/03/robert-cochrane-middle-pillar/
I know there's a version where the names NUIT, AIWASS, RA-HOOR-KHUIT, HADIT and BABALON-THERION (instead of the traditional Hebrew names) are vibrated at Kether, Da'ath, Tiphereth, Yesod and Malkuth.
If you want to move Current 93 energy via ritual through your body and connect to the god forms I think you're better off just doing the Star Ruby? And if you want to activate those same body points, it is essentially the chakra system so i would do a meditation/sensing exercise scrolling/moving qi through them... just my two cents.
Not necessarily by anyone related officially to the OTO or even GD.
