Let us not make this complicated.Road map for a certain place guides us how to go from point a to point b for that certain location. While a soul map is about the travel of soul from cradle to grave to so called after life.Soul of human is the being inside the person. We could say that every religion in the world has a soul map. So we may ask which is the correct soul map ? Unfortunately there is no trial and error here, wrong choice could lead to bad result. And right choice to good result.
My choice for the soul map is the Holy Bible. Have you tried to read it ?
