You Have a Soul Mate It is very common to travel through different lives with the same group of souls -- I call these groupings, soul mates or soul companions, or soul families. We seem to learn our spiritual lessons and accumulate or resolve our karma with our soul groups. Relationships may change from life to life, but the souls are the same. For example, your grandmother might reincarnate as your grandson. In this sense we never lose our loved ones, because we are always being reunited either on the other side or back here in physical bodies. In Miracles Happen, I describe many cases of soul recognition. In one case, Michelle, whose mother died when Michelle was a small child, was comforted to find that she and her mother were together before in the Middle Ages. They were husband and wife at that time. Brian L. Weiss, MD, is the author of Miracles Happen.
