Anybody Know About Sheldan Nidel?

He is sincere, but has no evidence that any of this is real? He's admittedly an introvert, which works against him but he sure comes across both sincere and a believable guy. Here's an interview it's off the deep end and & you will have to listen to much of this or other talks b/c judging this book by the cover will force you to miss some very interesting information. I've listened to several YT vids and his message is consistent and NOT idiotic like some others I've listened to. I'd appreciate your thoughts please. https://www.youtube.com/watch?v=ebd8TVr9m7g&feature=related
