1. Left: the Egyptian clay creation myth origin of humans,
according to which the god Khnum shapes two humans
from a ball of clay, then the goddess Isis
imparts life, soul (ba), and spirit(ka) into their composition,
via the power of the ankh. Right: the Greek reinterpretation
of this origin of humans model, as told by Plato, in
his Symposium (c.380BC), via the
voice ofAristophanes, according to which humans were
originally one body (akin to one ball of clay), with
one soul, but were split by Zeus, into two bodies and two
souls, aka split soul theory, thereafter forever being in
search of each other; thereby explaining the hypothetical
origin ofhumans.

2. In terminology, soul mate, or “soulmate” or “split soul
theory”, is an Egyptian-Greek religio-mythology, clay
creation myth based, origin of humans model, which posits
that humans originated in pairs, bound in one body, with one
original soul, but were "split" in two, supposedly for doing
something offensive to the gods, after which the newly
separated humans forever wandered the earth in search of
their long lost soul mate so to reunite their incomplete souls
and become one again.
Overview
The gist of soul mate theory, according to one account is the
story that: “our ancestors once had two heads, four arms
[and supposedly one soul]. They did something to offend
a god so that god punished them by splitting them down the
middle, resulting in the creation of humans. As a
punishment, we are condemned to spend our lives searching
for the other half, our soulmates.” (Ѻ)
Plato
Greek philosopher Plato, in his Symposium, via dialogue,
through the voice of Aristophanes, described the gist of long
lost split souls in search of each other, as follows: [1]
“The intense yearning which lovers have toward each other
does not appear to be the desire for sexual intercourse, but
for something else which the soul of each desires and
cannot tell, and of which he or she has only a dark and
doubtful presentiment.”
“According to Greek mythology, humans were originally
created with four arms, four legs and a head with two faces.
Fearing their power, Zeus split them into two separate parts,
condemning them to spend their lives in search of their other
halves.”
