The Bible (both old and new testament) is clear that KNOWLEDGE about God is pretty much readily available to those who seek it and that any "mystery religion" is bunk.
Kaballah, being loosely based on Judaism claims all sorts of special mysteries. That is bunk.
However there is an advanced discipline of Judaism known as nistar.
