Thanks for posting this Raum. Like you said, this info isn't really out on the internet. I recently read "Magick of the Ordinary" by Gershon Winkler, and this fleshes out some of that book a little more deeply (especially in relations to the 4 winds and their corresponding sounds).
I would add - the modern Qabbalah people practice isn't useless. It works well in some cases, but it certainly isn't traditional, and it's important to know the difference. This more traditional style is very helpful for me though, because it relates more to the core of my practice which is very shamanic (another reason why associating sounds to the 4 winds is interesting to me).
Thank you - I look forward to more gems (as well as the book I think you've mentioned elsewhere that you are writing)!
