Existence

We are born and reborn continuously because different people draw us differently. Those people we meet are given a lesson that helps us on our journey, but what if you are one of the people who will give them the lesson? As time goes on, I even lose track. This immortality-what does my existence really mean? It is a living thing that positively helps people's personal growth, or am I their karma, but I'm the one who got hurt the most? How will I go on when I don't have a clue what my path is? Give me an answer. Is my existence something I live for?
