Here he's supposed to go swimming in two lakes and then purify his mouth on the lap of an hermaphroditic god"dess"!!
That's funny, but which one was hermaphrodite ?
Gees, I don't know what your problem is. That text is perfectly understandable. Maybe you just don't get the context. Or maybe you have to be secretly initiated as a high priest to get the inside scoop. (sarcasm) It's like God, we can never understand his ways, it just is because the bible says so. Accept it, memorize it, preach it, and you will soon believe it.
You don't need to think for yourself, the egyptologists do that for us.
