As already mentioned spirit can ask and to some extent arrange a pre-destined life plan, this is done through prayer asking for the experiences that one wishes to have and what is done to accommodate this spirit is that they are put within a life here that by natural events will most probably have many of these things in the natural events of their life within the situations they live within and as I have said there is very little outside influence to change any of our lives here we all live a natural destiny within the natural laws and whether we have an old soul or not present our lives would be in most cases exactly the same. But on a very rare occasion such as in the case of individuals such as Moses, Christ, John the Baptist and others that have more directly work for the Father here there has inevitably been a need for some changes in their lives other than what would have been that lifes natural destiny, but these are special cases and not the normal way it works and each of their new souls was probably couple before birth with the old soul and awaken to the old soul before incarnation, so that the new soul could choose and offer to be of service in their lifetime here if they wished. In most cases there is no need for this as the present lifes destiny is not altered in anyway by the presence of an old soul, unless you're here to serve and teach like myself.
