Alan - I like that analogy, but when my computer crashes, the inference would be that I have some kind of malicious demon. - After multiple exorcisms of Windows I've finally gone on to Linux and now the machine seems better able to stay in a state of grace.

Blink - my point is that our purpose here has got to be more than sitting as inert lumps. Then looking at what we do, we can see that we bring back information about worldly life, and we also learn to get through life with fewer hangups. I think that there is more to it, and I think that the Egyptians knew it. I believe that if we die with awareness of ourselves as part of an eternally creative process, then we no longer live contingent to mundane factors, but can escape the cycle of rebirths. If we don't have that realization, then we can't go there to play that game, and we have to reincarnate, because our existence is contingent upon material manifestation.
I don't have any record of the Egyptian "justification" ceremony, but I'd guess that it is the negative confession made in the Hall of Maati. The implication of being "justified" would then be that there are no fetters to restrain us as we go into the Elysian fields in the afterlife. But without any knowledge of a place to go, we would presumably not know how to go there. The image of simply going into the kingdon of Osiris seems simplistic.
The Egyptians had a pretty good knowledge of basic number theory, and had discovered the sequence of sets that we get when we add things in every possible way - called forming the "power set" or "complexion" of the beginner set. This sequence interpreted as arithmetic can be shown to include all additive real, natural numbers. As a geometry it can be shown to include the eigenmatricies of all real and potential states, and thus is capable of not only reproducing itself, but also of extending the logical context to include a whole lot of cross-products that were not found in the beginner set. (EX: For set {A,B} we get {A, B, AB} which we call {A,B,C}. Then, for set {A,B,C} the complexion is {A,B,C,AC,AB,BC,ABC} - if we do it again we get 127 new terms etc.) In other words, the Egyptians had inowledge of a geometrical process by which prior states necessarily gave rise to subsequent states.
In the Hall of Maati there are 42 demigods and Osiris. A set of two terms gives rise to three terms, process, structure and relationship - as can be found by reading some of the texts. The total sins in the Hall of Maati can be broken down into these three groups - 42 sins of action which are denied, 42 sins of resulting structures which need not be denied if we deny the actions that cause them. And 42 sins of altered relationships, also not needed if the actions are denied. Hence, there are only 42 sins to deny.
At the same time, if we have not engaged in any of the 42 sins, then we are in line to continue to elaborate the logical connections by which we live in reality. Since this particular hyper-geometric progression both repeats the set of beginners, and also gives back every possible way to assemble them into outputs, it is a self-creative sequence. As a self-creative sequence, the soul that goes off into the spirit world and senses its nature to be part of the process being generated by that same self-created sequence will sense itself to be self-creating thereafter. As a self-creating being, it transcends its initial place as a material being dependent on mundane support.
In fewer words, the yogi who finally touches God in meditation no longer needs to reincarnate because the essence of transcendence is now available. Such a one is autonomous. Those who do not as yet attain to God will have to go around again.
