Probably, only a liberated 'mind' is considered worthy by the Creator to be saved and transformed to a higher form of existence. (Most likely other criteria must be met as well.) Here is how I envision this transformation. As much as I have thought about it, this was the only way I could imagine my 'mind' - soul/consciousness/bio-electronic file, or let's call it HUMAN OPERATING SYSTEM (HOS) - surviving the death of my body... and I might never have come to this realization without certain knowledge of computer technology. So: YOU, - not your body, but YOU, the HOS, which is as immaterial as a file on a computer hard drive – YOU are just as relocatable as a computer file. YOU function in your body as long as your body (the 'hardware') can keep YOU alive. As I understand it, YOU are about as superior to a computer file, such as a Windows Operating System, as the Creator is to Man.
......
We should probably mention dreams here as well... I believe that in the HOS there is a "video editor" just like, for example, in the Windows Operating System. The brain continually receives oxygen – the blood circulation never stops -, so it needs to do something while we are asleep. Our "video editor" kicks in and puts together various "presentations" using the accumulated information stored in memory.
Just like any other functioning, this "video creation" is not happening 'in the brain' but rather in the HOS that works on the circuitry of the brain. Similarly, a Windows video is created by the Video Editor of the Windows Operating System that works on the circuitry of the Central Processing Unit (CPU) of a computer. So, the brain (the CPU of the body) makes it possible for YOU, the HOS, to function – just like the CPU of a computer makes it possible for a computer Operating System to function. Of course, "hardware" and "operating system" depend on each other, they have a symbiotic relationship, one can not work without the other. It's not to say that YOU, the HOS, could not exist without a brain (and, of course, the peripheral support mechanism, the rest of the body). YOU could exist – while not alive – being stored who knows where by the Creator, just as a computer Operating System can be stored on a data storage device. Of course, it needs to be emphasized that an HOS is probably as much more sophisticated compared to a computer Operating System as the Creator compared to Man, that is incomparably.
