Babylonian-Satanic mysticism. Just like haZohar.

Putz haNasi and his ilk, all Babylonian sorcerer's. May they boil in excrement.

The MaHaRaL created a golem, that wasn't a "fairy tale" or a "legend". That was true, because he was an evil Babylonian sorcerer.
He is also a direct descendant of the necromancer and black magician Menachem Mendel Schneerson who is rotting in his hellhole called Ohel.
