well it's the first time i've heard this explanation of the souls inside the evas, and this one seems to make the most sense, it explains the chamber of Gauf which i used to not understand, also it explains the issue of the soul inside Eva unit 00... there is no soul necessary because Rei was the one pilot with a soulKenny Valencia's Translation for Eva Cult wrote:A long time ago God created the world, and to populated he created Adam and Lilith (This is the true biblical story which was changed by a priest, whose name I don’t know) but Adam and Lilith didn’t get along very well, they were always fighting. So one day God got angry and exiled Lilith to a deserted island... God then created Eve, she and Adam got along better, but God tested them (The forbidden fruit) and because they failed, God threw them out of Paradise. After some time Adam felt responsible for Lilith exile so he went looking for her in Earth, during the dinosaurs era, but because of a misfortune he collided with Earth... that was the First Impact.
Eons after, Seele found the ‘Dead Sea Scrolls’ were this story was told... they looked for Lilith and captured her, then they tried to capture Adam who was in the South Pole, sleeping. The humans not only wanted to capture Adam, they wanted to manipulate him and return him to his embryonic state, with which human kind could forge it’s own destiny. But God did not like the way humans were trying to change their destiny; and to punish mankind God allowed Adam to use his full power on Earth, thus causing the Second Impact... God then left mankind on it’s own...but mankind still pursued the changing of their destiny, so God brought froth His second punishment, which was to empty Gauf’s chamber, because of this everyone born after this date does not posses a soul, which means that neither Shinji, nor Asuka... or any other child born after that date would posses a soul. The only one with a soul is Rei Ayanami, who was given a soul artificially. This is the reason the Evangelions need a soul to operate, a soul to complement the pilot’s incomplete soul. This means that Eva 00 does not have a soul because Rei already has one, this is also why an adult cannot pilot an Eva.
Also, it explains the deal with Toji and his eva, since Toji is one of the children, he has no soul (chamber of Gauf is empty), so when he became the pilot of Eva unit 03, the Eva itself didn't have a soul, so that's what made it possible for the Angel to invade his Eva and take it over
Kaworu also is able to obtain Eva unit 02's services because Asuka was having problems and her mom's soul was hiding itself because it wasn't being accepted by Asuka
But, the one thing that isn't explained in that passage is that it says that Adults cannot pilot the Evas.. but if Rei can do it because she has a soul, doesn't that mean that adults can also pilot unit 00? or is it because she was the 1st pilot?
