LHP is a philosophy of what you use magick for - the tools and techniques are themselves neutral.
We are studying Enochian as a group on here if you want to join, and we have a bunch of book recommendations in that. Feeler thread for a Working Group learning Enochian magick
To use the Aethyrs takes a lot of study and tool set up.
Generally, as part of our studies so far, we find the works of Aaron Leitch, Lon Milo Duquette are excellent, and of course the original John Dee Diaries (probably those translated into modern English) are a good reference - but not the Scheuler’s work or Casaubon. The Scheuler’s kind of went thier own way and developed something Eniochian-inspired but not actually Enochian, and the Casaubon work is full of mistakes that are deliberate to discredit the work as Casaubon kind of hated them - it’s a politically motivated mess, according to Leitch.
If you want to skip the full methodology then the Gallery of Magick’s Success Magic book condensed it into ready to use workings.
