The reprobate failing the weighing of the heart found it eaten
by Ammit -- the great gulper -- and his consciousness thereby
annihilated as Jari said. At least this was the case by the New
Kingdom.
A question like this makes me feel the loss of my personal
library. Because of the nature of a hell people tend to shy
from discussing it or writing about it. If I could now check
Dr. Ben's Africa Mother of Western Religion or check any
copy of The Book of Coming Forth by Day I could verify
that AEs did have a Lake of Fire and what its function was.
Likewise I could examine a vignette where several female
figures are armed with long knives and under what
circumstances they were employed.
Sorry.
I don't recall a place of everlasting torture like the Xian and
Muslim Hell or even a place of regeneration like the Israel
Gehenna or Xian Purgatory. What I do recall from the Book
of Gates -- and in the very next vignette following the Herd
of Ra -- is that a measure of time was alotted for enjoying
an afterlife in "Blessed Fields." After that time elapsed
I honestly don't know what happened to consciousness.
