Query: I didn't find this book to be that profound.....

Yes, I am one of the few people who didn't find this book to be the life-changing miracle that many others did. I have read a book that tells many of the exact same lessons, has sold millions of more copies, and has been published and republished for hundreds of years. It's called The Bible. If you haven't read it, I highly suggest it.
