Awesome. Are the Cliff Notes out yet? Just kidding!
This type of endeavor must have been in favor at the time. The Kellogg family (yes, Corn Flakes, etc.), claimed the Urantia Book, a huge convoluted tome, was passed to a human by spiritual beings living on an invisible plane (among many) in the universes. I think they published it in 1955, but it seemed to be set mainly in 1930’s as far the likely time frame of the writing.
Hopefully this book is better than the Urantia Book, which was entertaining at first, but made a better doorstop than a life/spiritual guide. I check a link and see waht I think, thanks for the post.
