Ancient Domain
The bꜣ is not the Egyptian word for 'soul' in the modern, singular sense. It is the mobile, recognisable aspect of a person — the part that leaves the body at death, flies above the marshes, boards the sun-bark, and returns to the tomb. In life it is personality; in death it becomes the self that moves between worlds. Where the ka stays with the corpse and eats the offerings, the ba is the one who goes abroad.
