it seems that some people have the capacity to remember past lives naturally. Many children report memories from earlier lives. When times goes by and the child gets pulled to the present live by school and such, the memories fade away gradually.
Fourth jhana is the supreme basis for psychic powers, but they can arise from lesser samadhi. Even from pre-jhana samadhi. I can't remember my past lives at this moment, but I have a solid confidence in the teaching on rebirth.
