What If We Are All the Same Person?

What if we are all the same person, but we just look and act differently based on a multitude of superficial, external, and situational variables? What if the real point to existence is figuring out that not only are we connected, but that we are really just one being—that we all experience everything that happens to us exactly the same—that our only difference is what we experience and how that changes us—that all of our doubt, mistrust, hate, all of our longing for connection and our feelings of isolation and apathy are misplaced, and we actually could not be anymore alike or connected—that empathy for others is the closest we get to loving ourselves and the only emotion that approaches an understanding to our existence?
