Let's talk about the occult and esoteric traditions of the Abrahamic faiths, whether their origin is in that faith itself or from some outside source. Unfortunately, I am not that knowledgeable on this topic (which is why I made the thread), so I don't have many resources to jump start this conversation. Some interesting things that I find to be worth checking out, though:
Islam
Recently found this Wahid Azal guy on youtube, and he puts forward some interesting points of view. Video is embedded, but look up his channel and his blog as well. He is a Shia Muslim who has started his own Sufi order.
Judaism
The only resource on Kabbalah I know is the author Gerschom Scholem and scant references to the topic in some of Evola's books. I would appreciate good resources on this topic as I am very curious about it. Other than that, I'm familiar with Maimonides' book Guide for the Perplexed, but if I'm not mistaken that's just Aristotelian philosophy concealed by a Jewish exterior. I think Nahmanides was the more mystical medieval Jewish thinker, but I don't know much about him.
Christianity
I'm familiar with authors such as Macarius, and I would particularly check out his Spiritual Homilies. I personally have only browsed it, but it seems worth checking out. The Ladder of Divine Ascent also seems interesting. The only work I can think of off the top of my head that I've actually read (several times, actually, it was fantastic) are Gregory Palamas' Triads. But that isn't an exposition of the esoteric Christian tradition as it is a defense of it against the "rationalists" of his era.
