Egyptian soul

Akh

The Akh ("to shine") changed somewhat in the history of Egyptian belief. It was, at first, the unchanging unification of Ka and Ba, which united after the death of the physical body. In this sense, it was a sort of ghost. The Akh was then a part of the Akh-Akh, the panoply of Akhs from other people, gods and animals. Alternatively, the Ka changed into the Akh and Ba after death, rather than uniting with the Ba. In this system, the Akh went to the underworld and became the Ka again, while th Ba remained on Earth in the corpse of the deceased.

Ka

The Ka was the spiritual soul of a person or a god, a type of mana. The Ka was created by Mesenet along with the physical form of the person, and then continued to the underworld after the death of the physical body.

Ba

After the death of an individual, the Ba was the shell or physical body that remained on Earth in its tomb. At some point the Ba was to reunite with the Ka and thus the body was mummified. Should the body be destroyed it was believed that a stone sculpture would suffice.
