To be truthful I just started picking up books at the media centre about anceint Khemet, and to be quite frank you started the spark. I found one book by G.I. Gurdjieff who explained the slendor of Pre-sand Egypt in a way I almost lost my breath. Its basicly an Esoteric Book but none the less informative. Believe me once I beging studing a subject I like to get deep into it and try to explore all of its facets even if I will never adhere to it. Its nice to learn something new. It helps to understand ones brothers so as to live in greater harmony.

Concerning Kabbalah Someone went into the desert caves to meditate on the one Divine. When he came out the Kabbalah was born some time during the 10 century I think which is relatively new compared to Haggada(Not to be confused with Haggadah).

Pre-exilic is before the Babylonian expulsion Post-Exilic is when King Cyprus let the people return. It has nothing to do with Egypt. The difference is that the two sides have become seperated.

Pre-exilic have no afterlife all is today and if there is your works will count you worthy to the next.
There is no messiah to be waited one to deliver the Nation of Israel. Israel is to defend itself.
There is no satan, any evil is produced by mankinds falliableness. There is no evil in the Creator for He/She is perfect balance, when judgement is poured out its been coming a long time.
The Tanakh and Deutercanical books of the Mystic prophets are holy and no other book aka the rejection of the talmud and other ravvanical books.

Post-exilic have an afterlife
they expect a messiah to bring about world peace
they have a satan but not similar to the christian one. satan is a lawyer or prosecutor in the judgement court
God is exculsive therefore thier views are imbalanced with scripture.
The Talmud/Mishna superceeds the Tanakh therefore abandoning our promise with the Creator not to add or remove from the scripture.
