Practical Kabbalah is more along the lines of ceremonial magick wherein success is highly subjected to the materials, sigils, intonation and prayers being in harmonization with the Will, very akin to John Dees Enochian system. Hermetic Qabala included
where as this "Authentic" Kabbalah dubbed as Lurianic, is much more invested and pure in its nature drawing current almost solely from Isaac Lurias biblical commentary and contribution on "Holy" Jewish texts ,i.e.. -Sefer Ha Zohar -Torah .etc. whose purpose is to correct the desires of self to attain the upper worlds from which all things stem from and are ironically concealed from our senses. attaining the equivalence of form to GOD/ADAM by group study/bestowal reveals the essence of our soul though *US* and corrects our individual state to that of a Whole Soul. which is 1 of 600,000 in existence.
As for the Shem Ha Mephorash, Realistically its as practical as it gets. however, invoking these names without proper preparation or selfish desire will do nothing at most, and Humiliate you at worst (or best). Considering you must exist at a very high spiritual state to even attract the Kedusha therein. Mind you that Moses used these forces to bring an entire nation out of bondage. HaShem and he worked the impossible, thats because he represented Chokmah, pure bestowal for the sake of the creator, The Point in the heart must develop to pure altruism and all gain for the sake there of.
So remember, What you put in is what you get out. Shalom
Thanks for the comment, your very knowledgeable on the subject, very much appreciate the comment.
Im in contact with mystics to learn more, i attend Shull regularly, wear tefillin and all (my hebrew is getting better), im careful about crossing he lines with Avodah Zarah....
Now im not saying im perfect, just that most jews learn to prepare themselves for these rituals
As for John Dee and Enochian stuff its not Jewish at all and may fo been motivated by antisemitism, not exactly Dee but many seeking hold upload a prophetic identity during medieval times, it was sort of like saying your superman, no surprise why jews believe tat allot of christian tend to fantasize having super powers, etc,
While on the subject i lie to say that i dont get is why people copy or take stuff from Judaism or any other tribal religion when they can simply join another nation through initiation or conversion, circumcision is nothing compared to the suffering people go through to join other tribal nations.
