Everyone is where they are meant to be. There are no mistakes. How can a mistake happen when God is One, All there is? Can anything be outside of Divine order? It can appear that individually or collectively we have taken a "wrong" or "backwards" turn, and the world certainly appears like we have taaken a lot of wrong steps, but these are appearances that will go to nothingness once we recoginze our relationship to God. You can't change the eternal --- you can't change what never happened. What changes is our recognition that this dream of separation was just that, a dream from which we can awaken any time we choose.
