So I ve been thinking of the egyptians a lot due to them being the new guys that are meeting Solus and Griffon (which were mentioned in the thread), and their rituals that were designed for the funerals, including the preservation of the body and soul. And then I thought about the ability of the heroic heart to continue even in death which is also a requisite to become a god in the original setting. So when I fused both together I came to the conclussion that one of the requisites to obtain an apotheosis is to well die. Then I remembered that one of the ways tyrants are refered are as beings trapped in prisons or who have oversized clothes which they are unable to fill, but spiritual beings dont have the same limits as physical ones.
There is an egyptian part of the soul called called Akh or Ikhu in which the Ba (the personality, the passionate heart, known to be used to visit the gods (divine?), lingers too in the physical after death, passion) and the ka (vital essence, sustains through food, needs nourisment, eats offerings, probably hunger) join together in death to form it, which represents intellect and it said to reside with the gods in death, if we combine this with the theory of the 3 parts of the soul of Plato, we coul translate it by saying that the intellect takes control of passion and hunger and joins them together after death into something more divine than in flesh. Then I hipothesize that they have to use the natural connection between body and soul in order to return to their physical bodies, use their last breath of pneuma with their accumulated heartblood that they have and can adquire through offerings in order to refine the mumified body into one of prima materia which combined with the divine self would create something divine in nature.
I ve found also correlation with the other 5 parts of the egyptian soul (as the body is considered one of them) and how they might relate to this. We have Sekhmet also known as life energy which probably relates to pneuma, which also explains how is related to Akh, as one can only use pneuma fully after becoming a philosopher and knowing reason. There is also the JB which is physical manifested as the heart, which is weighted in deth to be judged, which probably correlates with the monument of ego which allows one to pursue virtue, cultivate pillars and heroic deeds, and in which heart demons reside which probably is related with the egyptian demon/spirit Ammit. Sheut is probably the subconcious (as we can see its use in virtous sons) and probably also connects with the collective subconcious. Ren is probably related with the Mahabrian souls shapes and Platos theory of souls, but also is probably one of thhe requirements to adquire a domain, as its acts as a spiritual core and symbol of everything that souls represent. Not ony that knowing a true name of a god or a physical phenomenon can allow you control of the entity or power you are calling, which probably relates how a god adquires a divine domain or creates a divine soul.
