To the Ancient Egyptians, the soul was the most important part of a person and it was separated into different parts making up it’s vehicle (the human, it this case). There was one physical form and eight semi-divine parts which made up one’s soul. As far as archaeologists and egyptologists know, these parts are labeled as follows:

The double that lingered on in the tomb inhabiting the body or even statues of the dead, but was also independent of the deceased body and could move, eat and drink at will. Kind of like a doppelganger but not evil.

This was the immortal part, the radiant and shining being that lived on in the Sahu, the intellect, will and intentions of the deceased that transfigured death and ascended to the heavens to live with the gods.

The heart, this was the source of good and evil within a person, the moral awareness and center of thought that could leave the body at will, and live with the gods after death, or be eaten by Ammut as the final death if it failed to weigh equally against Ma’at.
