Those of you that read this will of course be familiar with Admiral Byrd getting his ass handed to him on his trip to the Antarctic. The ultimate rabbit hole mystery of our planet and life on "other worlds and dimensions" The spirit world is not what people think it is and it is very much aligned to this mystery. Our souls do not leave this planet, they are held prisoner in a sort of Faraday cage until forced or manipulated into reincarnation.
I have never bought in to the flat earth stuff that is popular at present. I am open minded, but I wait, watch and learn first and foremost. This book however is quite something.
