I guess we need to know fact from friction.
In the book, Shambala is both a place and a "spirit".
There is the outer rings and the temples. The people create things with their minds. Their doors are made of force field . They have generators to help them amplify the ability to create most things by using the mental powder. They are also expending on the eleventh insight which is about prayer fields.
Their purpose is to cause an awakening in the outer cultures (us). The ulimate purpose is to rely more on our mental power and to fully understand how the more evolved people at Shambala live and why.
They are a race that eliminate fear and hatred. They increase the prayer field to help enlighten and uplift the others. I.e. a better and more conscious society will evolve.
ps: I was curious if we can actually go there and see for ourselves.
Thank care.
