One interesting bit in the Ra Material is the story about the Ark and its contents. The suggestion is that the Ark contained, not two stone tablets with ten commandments but The Scroll considered by Moishe, most holy, and other accounts, of the beliefs concerning the Creation, whereby the Priests could draw power and feel the presence of the Creator. However it is to be noted that the entire arrangement was designed not by the one known to the confederation as Yahweh, but rather by negative entities preferring this method of creating an elite called the Sons of Levi. The results for the negative however were mixed, as this object of power, became completely positive, as originally given by Moses, to those in harmony with the experience of service to others, untarnished by unrighteousness and separation.
It is the same case in all of our orthodox religions, which are all now somewhat mixed in orientation, yet which non the less can offer a path to the One Creator for the pure seeker. It is also said that the Ark is still in existance.
