One thing everyone chooses to forget about the Pyramid Texts is that it is about the great pyramids and by extention "The Great Pyramid". Just because our earliest copy dates to a slightly later time changes nothing. The same people who built the Great Pyramid wrote these utterances and you can gain insight into their thinking and beliefs by studying them. It's irrelevant that Egyptologists have chosen to ignore the passages that support alternative beliefs because those passages still exist and there are numerous ones that support the RVT. My interpretation does not well support the RVT theory but my interpretation of THEIR words is just as irrelevant as Egyptological interpretation. The ONLY thing that counts is what the authors meant and their actual words support this theory.
In my interpretation the best support is the line "He, he is the pyramid he protects". The pyramid is the king according to the words of the builders and the concept of "protection" might easily be interpreted as the RVT. It hardly stops here since no one really knows author intent and most people just take them as stinky footed bumpkins with nothing important to say. They still said that Nut was the granary. This could be a reference to the seed crop high up in the kings gallery. They said the the earth is high under the sky by means of the arms of Tefnut. I'm sure they're wrong but Egyptologists believe that Tefnut is the goddess of moisture and that she existed in a state of latency. This could be analagous to stored seeds and a statement of the reasons the pyramids were built.
I might work on this a little later if there's any interest but for now I just wanted this thread back on top.
