I certainly understand this.
The problem is the same as it's been for years. People can't take what's written in the Pyramid Texts at face value. The problem is the very nature of language. We always pick definitions for words as we read or listen. Sentences make no sense unless we pick the right definitions and this process occurs in real time without being noticed. It's the nature of our language and how we communicate.
But it is not the nature of ancient language so if you do it then the PT will make no sense. Every single word had a single definition and every single thing had three words that applied to it; a scientific word (we mistake for gods), a colloquial word, and a vulgar word. It was through the choice of words that meaning was expressed.
The similarities between the languages are still sufficient to understand the most general concepts when they are repeated enough times. Since the king's ascension to heaven is the subject of these rituals the concept of the pyramid and its function are repeated many many times. The pyramid is the ka of the king and his tomb is in the sky. It does say this over and over and some are easily comprehensible even if you don't understand the language. Part of the difficulty of seeing this is the ancient language didn't use statement to express meaning but rather defined a context and meaning was apparent in this context. No matter how you cut it or parse it they still said the king didn't rot in the ground and that he ascended to the sky which was his tomb. They said he ascended from the pyre (iskn) on the east side of the pyramid. Of course I only know the iskn was a funeral pyre because they said this was the origin of the smoke that went to heaven after the the incense is laid on the fire and it and the king become one. The living king's mummy is freed from his bandages. This isn't "belief" because they didn't believe he was "alive" in this sense. Like all people he lived until he was forgotten and the pyramid would help people remember.
It wasn't death that was important to the ancient Egyptians, it was life. And one of the terms for pyramid was "house of life".
