It sounds somewhat like a bunch of lawyers attempting to get their client through in good order.
Otherwise not too much here. It can be recognized as an early view of the other side. What it does do is remove a lot of the mystery regarding what the priests actually did then for the dead. i also suspect that the so called Egyptian cult of the dead is hugely overstated..
This item is clearly an extended funeral oration and prayer spoken over the body of a deceased Pharaoh. It is interesting as it describes the understood cosmology of the other side and clearly sees life a a pilgramage through this vale of tears.
