As for the Kaballah, most of the website (finally got it working) loves talking about Kaballah in insanely vague terms. The structure of it, the goals of it, what it isn't, etc. But not actual beliefs. And it refers to itself as a "science" so often that you get the distinct feeling it's trying to convince us that it's legit through sheer repitition.
It claims to be a guidebook for interpreting the spiritual, just as physical science helps us understand the material world. I'd love to see their proofs for the existence of these spiritual aspects of life, because they didn't offer any in the free material available (though they like trying to sell me books). I'm not saying these arguments don't exist, but they certainly aren't forthcoming with them, and seem to rely on an assumed acceptance of the existence of something "spiritual".
They also borrow heavily from writings and stories of Abraham and Moses, which makes it another branch of Western Abrahamic religions (Judaism, Christianity, Islam) and thus subject to the same problems with inconsistent morality and myhological predecessors (and thus historical validity).
Judging just by the initial pitch, it seems far more practical and rational than many mainstream religions. But I can't say I know any of their specific beliefs, because once again they don't seem to want to discuss them much. Sure, if I really want to learn about a religion I'll read a bunch of scholarly works, but is it so much to ask for a basic outline of teachings and belief structures?
