Vortex Healing for instance is a cluster of bad New Age Clichés. Yet, the person I first learned about it from, a very serious occultist, was floored at its results. After checking it out I found other people who didnt buy into the whole new age history of "Merlins" and such, but who attested to its absolutely shocking effectiveness. After looking at some of the tech, a bit of it seems to mirror things I have been taught by angels (a new age cliché in itself). One of these days I will investigate further.
Another topic that has gotten a lot of attention recently in some quarters are old Parker Press books like The Miracle of New Avatar Power. These books are 25% tech and about 75% hokey testimonials like "How Charles F made $10,000 after performing the invocation to give secret knowlege". But heres the thing: the modern mages that are using this book and others like it, are reporting exactly that kind of success on their boards. They aren't selling the book. The tech is pretty simple, solid kabbalistic root - but just a bit different in terms of names and such. Different enough that those who cleave steadfastly to the standard will be turned off, but those that recognize how little actual instruction from angels and spirits actually sticks to those standard will see that it is a sign of validity rather than not.
Even some standard mages have made these changes. For instance William gray has most of the Sodalities invoking Jivroel instead of Gabriel because it tones down the martial elements of this angel, which was important in the days after the world war. Should we still be doing it that way? I suppose somebody should ask Gabriel or Jivroel, but instead we mostly just follow Grays lead so that we are all on the same page.
Anyway, as my own course in magic is about to start up, and is already approaching 40 students, I am becoming aware that a few of the things that iI will be teaching in later lessons, wont necessarily follow the standard because they have been taught to me by spirits or discovered through experimentation. I hope that they dont come off sounding like Vortex Healing does, but I am also proud that the material doesnt just fit snuggly into the mold.
