A MUST HAVE FOR EVERY LIBRARY, INDISPUTABLY!This book has a fantastic compilation of experiences from general authorities and modern day prophets. I can't believe I have missed so many truths before because I did not carefully study the standard works and teachings of the early prophets. (I do not believe these things because the author tells them to me. I believe them because I have been searching for the key to unlock my understanding for so long I instantly recognized it.)It is definitely for an LDS audience and those who are not will not likely appreciate the links within unless they are searching for an understanding of gospel truths and are open to all denominations' input. I could not put this book down.Cons: I found the first half of the book irresistible, but past that, my interest started to wane and I felt I could do a better job searching the rest of heaven's mysteries on my own. The second half of the book has lots more, what I would call, speculation, but anybody who isn't half asleep and who pays attention can decipher for themselves when the author is opining and when the truths are so blatantly obvious only a moron couldn't see it. If you're the person, however, who has never really looked for the truth and don't want to find it very bad, or if you just believe whatever someone tells you, the I recommend leaving this one alone. Maybe this book isn't for you.
