What I'm getting to, melon, is that perhaps instead of questioning how the Zoroastrian beliefs may have influenced Judaism, and Christianity, you should be questioning how Kabbalah perhaps influenced Zoroastrian beliefs, and how Kabbalah influenced others.
Now, if you go poking around on the net, or even most books, you're going to find that Kabbalah surfaces after the exile... but don't be mislead. Kabbalah was not to be taught or discussed among those that did not pursue it on their own. It is something within, which leads me to this...
Personally, I feel that most people can't understand what Kabbalah really is, there are currently tooooo many misdirections (which is ironic, seeing as though it's not supposed to be taught, etc). BUT... if you want a pretty good interpretation, just look at George Lucas' The Force.
Unfortunately, as far as Kabbalah goes, I've got no great web sites to quote for you melon, no great books to quote either... what's written is misleading, fiction, assumption, flat out wrong, and is simply that... written.
Language is mans gift, and tragedy.
