I though it best to use as little words as possible. I will try to teach you all that can be learned through imagery alone. Egyptians highly prided themselves about the afterlife and had a strict path that must be followed if a person is to pass into the next world without something going wrong.
On the right is the prepartion for the afterlife and the left is what the egyptians believe are the three parts of the soul. (From top to bottom) Ba, Ka, Ahk.
These are the first five stages of the afterlife. You enter at sunset and have to travel through the different section with each passing hour.
For mortal souls the journey ends here with the weighing of the heart against the feather of truth. If their heart is balanced with the feather then they an enjoy death, but if not then their soul is devoured. Ra has to continue on through the night and finish his journey after he kills the Chaos Serpent Apophis.
