The rating is for my personal enjoyment of having read it.
On the one hand, overall it was very interesting and the beginning bits about the Creation, Fall of Lucifer, fall of man, etc gave me some aha moments. Also, I did feel the stirrings of "ah, yes, I should try to be a better person", and the nudges in that direction are a good thing for me.
On the other, it's incredibly lengthy (not a bad thing in above itself) but it does get repetitive or go off on tangents that, while perhaps worthy or edifying, didn't seem...necessary. I did look at the abridged version and it cuts out 75% of all of the volumes, and that was too much. It also cut out a lot of the good stuff from this volume, and that didn't make me want to read it in place of the next few volumes.
I don't know that it brought me any closer to a love or appreciation for Our Lady. She appears, especially in relating her youth, as merely solemn and, well, boring. She also does not come across as human. I know she is and never does it claim that she is NOT, but she doesn't come across as having natural joy or happiness or silliness. The only emotion she seemed to exhibit that was related to anything dealing with this world was sorrow when Anne and Joachim died. I can believe that Mary acted "less human" because she was so holy and so attuned with God, but it makes it harder to connect with her.
All I was getting from portions of this was "the world is evil, everything in it is evil, think only of God, take pleasure in nothing that is remotely of the world." But we are human, we are meant to be loving and silly and enjoy (within reason) our food and our sleep and our hot showers and a warm summer night with a sky full of stars; good company, a lovely book, to play with our children, to love our spouse, etc. While thinking of God only IS a worthy thing that doesn't mean that simple pleasures without being taken out of proportions are in any way wrong. And also, most people are not cloistered nuns or monks... but Mary is supposedly relating all this to a nun so I guess maybe it's only meant for her?
In the end, I tell myself, if I read something that helped or guided me or made me understand something better, I'll take it and use it and be glad for it. If it didn't help me, let it go.
