Book of Thoth - Tarot

[anagogy]

Original Kabbalah is an integral part of the Jewish tradition. This is the study of inner dimensions of Torah. Maybe you don't have to be Jewish but it makes sense that observances and knowledge of Jewish Law are prerequisite. Some also say you need a teacher to guide you.

I'm quite aware. But just because I predominantly study Lurianic Kabbalah (a Judaic tradition), doesn't mean I accept all its idiosyncrasies. There is distortion there (it's not perfect), just not as much distortion as the other traditions in my opinion.

Ra sometimes mentioned the four classic elements: fire, water, air and earth. This concepts look simpler than other systems. Is there any value in studying this?

Yes, there is extreme value to be found here. In fact, deeply understanding the elements is precisely the key to unlocking the gateways of the tree of life.
