I think its complicated the same way rabbis complicated every step about Tefillin to lock one into a meditational state or basically be focused.,
however, this magick including rabbi luria etc is not advised to a none initiate, and a initiate in the correct use of a system related to enoch and or shemhamphorash requires one to be one to be at-least circumcised or born Jewish, all systems have a initiation and Abrahamic sources require one’s bond with the eternal to not fall short of been tricked by shadim or other entities around which where banished out of site from man kind aka Adam on the 7th creation day Shabbat.
But do what you desire if its your path, anyone was allowed to watch the sacrifices and other rituals during the temple times, its written in a number of sections throughout the Torah.
Funkyman, what do you mean? This is Enochian work brother, and not rabbinic work. I could not see anything about Rabbi Luria there...And I don't agree with your thought about it is cheap. Who says expensive books are good? So then do you buy only expensive books? Give me an example of a good book.
Why complicated? Also we have many claims for Kabbalah that is complicated but it is not. I will say contrary: both Enochian system and Kabbalah are simple. But if you want primer of really complex and heavy text with out of measure complications please check out this book Lucifer: Princeps.
Surely this new book from preview seems interesting and I would recommend it. From older titles classics: Enochian World of Aleister Crowley, Vision Magick from Duquette and For Beginners by Donald Tyson will be enough for some time. I mean basic system is easy to understand, you have classic pyramidal structure and you learn the names or read them. What could be more complex is making of material tools but that is also easy.
