There is a little known talismanic technique for charging your talismans (or yourself!) with an exponential level of energy. The reason why this technique is still almost unknown today is because it only has been published twice: once 1928 without any textual explanation and again 1971 with a more elaborate analysis of its use and application. However, both publications are in German language and I couldn't find any reference to it in English literature yet.
The technique originated from the inner lodge materials of the OTO and later theFraternitas Saturnis. Over several years I have successfully worked with this technique - and needed to tame the energies it created for clients on several occasions. That's why when I call it 'high voltage' it's to emphasize the source of power and risk it gives access to in equal terms...
You can find the full instructions on how to create a sigil from this technique - called the Glyph of the Moon - in this article: http://www.myoccultcircle.com/the-glyphe-of-the-moon/
Handle with care - and enjoy the ride!
