The previous three books in the series were so well done. I had the pleasure of listening to the audiobooks, and I got a lot out of them. I encourage you to pick them up or give them a listen. Unfortunately, I can't say the same for this book. Maybe it's just me, or perhaps I'm just not on the same page (pardon the pun) spiritually as this book, but I simply just didn't "get" it and it didn't resonate the same way as the others did.
What I did like was the question and answer section, there was value there, it was well executed, and tied the books nicely together. There were some interesting and thought-provoking sections, but there was a lot that was just lost on me, and I felt like it was just out of my reach.
