Would it be possible to evoke historical figures to communicate with them, possibly invoke them, and even have them use their talents and skills to help you out in your life from beyond the grave?
For example, would it be possible to evoke the powerful Soviet leader Joseph Stalin, and if so, in what ways do you think he could help you out?
I would say try it. I can not say yes or no. Hey give it a go.Personally I do not think you are getting in touch with a true spirit but hey do your own thing.
So I guess I am saying you are stretching things to far.
Joseph Stalin is a human. They reincarnate and they are also not gods. I think if you want knowledge you need to look elsewhere
