This place is called the archive of mind; many prime organizations have it.
The man sitting inside was dead, but he had preserved his knowledge and experience for the people to look at.
Not just look at it, but also experience it.
It might seem like imprinting, and it sort of is, but unlike imprinting. The knowledge doesn't imprint on the people. It is just give them, the complete experience and what they gain from it, is up to them.
One needs to be a prime for it and practice a very difficult method.
Which is essentially a recording method. It records the experiences, memories and knowledge you want to share and if what I read is right; it took a lot of effort, and one needs to have a strong soul energy for it.
Primes live for thousands of years, but they are not immortal; they die eventually.
