pt for sky (upper world) - realm of the akhu and the netjeru
ta for earth (middle world) - realm of the living
imHt for netherworld (lower world) - realm of the dead
I'm confused. How would the ancient Egyptian word for sky correlate with a "shamanic" understanding of the upper realm, and ta for the "middle world"? Isn't this just transplanting Egyptian words for concepts that don't really correlate? I have never heard of anyone in ancient Egypt taking a "shamanic" journey to the sky except for late priests of Amun viewing the sky from a staircase during initiation ritual. Even then I'm not sure that this would qualify as a "shamanic journey."
Also the earth is not just a realm for the living because it is understood that the deceased ancestors would not only inhabit but affect the living.
