I actually read that book and thought it was really interesting. I actually had thought of this before, because I been trying to incorporate the LOA but was confused because of the books that I have read saying our lives are already planned. The way I see it is that we choose like a certain theme in our lives. Kind of like when we choose a subjects when it comes to learning. I believe that they're some things already pre-planned before we come here, and the other half is made by our will. In the book it said that some things are not planned, one story about this persons past incarnation. It said that his death was not planned but the soul of the body couldn't bear the pain of the incarnations body and decided it was best to go back home.
