Yes ✌🏼
Could you recommend any book or documentary about him?
I wish I could! I read a really good book about him, but it was about 15 years ago and I honestly don't remember what the book was called or who wrote it. 😬
It might have been this: https://www.amazon.com/There-River-Story-Edgar-Cayce/dp/0399172661 The name of the book sounds about right but the version I read had a different cover.
