I have been at it with the Enochian Heptarchy for over a year now. I have evoked all of the Planetary Kings and Princes at least 3 or 4 times each.
I was wondering if anyone has experience in this system, and if not, I have to highly recommend it. Having been through the evocation of a few of the Olympic Spirits in Arbatel of Magic, as well as an experiment here and there out of Juratus, I have to say that my results with the Enochian Heptarchy have not only been more intense and strong, but also clear and clean.
I began simply without all of the required tools, and just kept adding more and more into the mix as I was able to acquire and make them. I won't even begin to describe the things that occurred that I found I was experiencing as miraculous.
But I am unsure if anyone else has ever practiced this as system contained completely within Dee's 5 Books of Mystery and Sloane MS 3191.
Someone else should do some experiments and post here ... !!!
