Query: The Celestine Prophecy - The Tenth Insight - Secret of Shambala

I love the 1/st book: "The Celestine Prophecy". Is one of my favorites books, ever. I was absolutely delighted while reading it. I found it very spiritual, motivational and inspiring, without being religious or else. After a few years later, I found it in my library, and need to read it once again, with more understanding than the first time. After so many years, I still recommend these meaningful book.I also read the 2nd book: "Tenth Insight", from the same author, but liked the first book more than this. The author published another 3rd book in this serie: "The Secret of Shambala...". Maybe it has too long and hard to follow narratives, maybe it was written in another style, and I cannot really appreciated it and grasp the message the author was trying to deliver to us. The third one is the one that I really disliked.Books:The Celestine Prophecy - The Tenth Insight - The Secret of Shambala
