Did the the Egyptians seperate "Reality" from the other "spiritual reality"? No. Rarely.

Humans were not seperate or alone from the universe, even death, which being sacred was, deeply connected to our short stay on this "place" which could change into a different place, a mystety of transformation.  It was not a follow a linear line experience, and expanding was hoped for.
The eternal was here, duality: not actually duel natured, evil being fairly outed through history, changes to return that maybe, not entirely missing, imperfect, yet a clear picture of ethics was there.

Something Here and not a precise definition.
