Did you check out Franz Bardon and his works? I read "Initiation into Hermetics" and I'm impressed how he in a very good way explained tetragrammaton, four elements and much much more. What do you think of him and his works?
The 10 steps on the Path of the Magician is an incredible journey and not too difficult at all . This is in IIH but the Key to the Qabballah has more obvious errata . If there are errors in IIH I have found nothing major yet . I love FB!
His book IIH teaches control of the hermetic elements , how to begin the emerald tablet and how to begin the kabballah . This is a great first step for any magician .
I actually found it extremely difficult !! So much so, that I only managed the 1st stage, and that took about a year. I gave up soon after.
FB does say however, that time is not of the essence - only proceed to the next step once you're happy with the last. Some people can complete it fairly quickly and for others I guess it may take a few years !
Maybe I'll give it another go one day.
