Ka and ba: the Egyptian soul in two signs
14 October 2026
The Egyptians had no single word for the soul. They saw a person as several parts, and two of them have signs you will meet in every museum. The ka, kꜣ, is the life force, written with two raised arms. The ba, bꜣ, is the personality, the part that can move about after death, drawn as a bird with a human head.
After death the ka stayed by the tomb and lived on the food offered there. The ba flew out into the daylight and came back to the body at night.
Two raised arms write the ka
The ka sign is a pair of arms bent upward at the elbow, palms facing out. Scholars do not agree what the gesture shows. An embrace and a gesture of protection are the usual readings.
The ka was what separated the living from the dead, and it came into being with the body. In the birth scenes of Hatshepsut's temple at Deir el-Bahari, the ram-headed god Khnum shapes the baby on his potter's wheel together with her ka, two small figures side by side.
When a person died, the ka needed feeding. Offering texts give bread and beer n kꜣ n, 'for the ka of' the dead person, and priests called 'servants of the ka' brought food to the tomb chapel. The pun helped: kꜣw, 'food', has the same consonants and could be written with the same arms.
Kings named themselves after the ka of Ra
Kings put the ka of the sun god into their throne names. Menkaure, builder of the third pyramid at Giza, wrote mn-kꜣw-rꜥ with the sun disc for Ra, the game board for mn, the water ripple as a reminder of its n, and the raised arms three times: three signs make a plural, kꜣw, 'kas'. Read in order: 'eternal are the kas of Ra'.
A ka statue gave the ka a body to live in. The most striking one belongs to King Hor of the Thirteenth Dynasty, around 1750 BC: a wooden figure found at Dahshur, with the raised arms of the ka sign standing on top of his head. It is in the Egyptian Museum in Cairo.
- mn-kꜣw-rꜥ, Menkaure: eternal are the kas of Ra
- nfr-kꜣ-rꜥ, Neferkare: beautiful is the ka of Ra (Pepi II)
- ḫpr-kꜣ-rꜥ, Kheperkare: the ka of Ra comes into being (Senusret I)
- mꜣꜥt-kꜣ-rꜥ, Maatkare: truth is the ka of Ra (Hatshepsut)
The ba is a bird with a human face
The ba is what made someone that person and no other, with the power to move and act. For most of Egyptian history the word bꜣ was written with the saddle-billed stork, a sign with the same sound. Pictures of the ba as a falcon-like bird with a human head appear only at the start of the New Kingdom, and from then on it is the familiar form.
The ba needed the body as a home base. In Book of the Dead copies it hovers over the mummy on its bier, and spell 89 is for letting the ba join its corpse. That spell asks for a golden ba bird laid on the mummy's chest. One made for Psusennes I and found in his tomb at Tanis, beaten gold, wearing the royal headcloth and cobra and gripping shen signs in its claws, is in the Egyptian Museum in Cairo.
Gods had a ba too
Gods had bas too, and the plural, bꜣw, came to mean power or impressiveness, the force of a god acting in the world. The word for ram also sounded bꜣ, so rams could stand for the ba of a god. At Mendes in the Delta the ram god was Banebdjedet, 'the ba of the lord of Djedet'.
One of the strangest Middle Kingdom texts, the Dispute between a Man and his Ba on Papyrus Berlin 3024, is a dialogue between a man weary of life and his ba, which argues with him about death and how to face it.
The right rites turned the dead into an akh
A third word completes the set. The akh, ꜣḫ, written with the crested ibis, is the 'effective' spirit of a dead person who has passed into the next world. In the account most textbooks give, the ba and ka reunite after the right funeral rites and the dead become an akh. Akhenaten took the same sign for his name, 'effective for the Aten'.
Other parts of a person had their own words: the name, the shadow, the heart.
The pad compares your ka and ba with the carved signs
For the ka, draw two upright arms joined at the bottom by a straight line, each bent at the elbow, with the hands open at the top. Then try the ba bird: a falcon's body and tail with a small human head. The pad shows how close each comes to the carved sign.
Questions
What is the difference between the ka and the ba?
The ka is life force, passed down from parent to child, and offerings were addressed to it. The ba is the individual person, with a will of their own: it is the ba that the man in the Dispute argues with.
Is the ka a double of the person?
Older books often translate ka as 'double', because it is born with the person and statues of the dead served as its home. Most Egyptologists now prefer 'life force' or 'vital essence'.
Why is the ba drawn as a bird?
Birds can fly up out of a tomb shaft and come back, which is just what the ba was meant to do. The human head shows whose ba it is.
What did 'going to one's ka' mean?
It was a polite way to say that someone had died, since at death a person joined their ka.
