Open Individualism?

What if we are all collectively one? All sharing the same existences. Loving, lying, cheating, learning? What if I am you and you are me? In different incarnations of reality. My light is your own. Your shadows are mine. Our lessons are ours. We’re all deceived with false perceptions of time. How wonderful, how horrible, how wretched to think! That every person I’ve judged or hated or harmed was part of the same soul fabric and in sense I have cut my own arm. Every person I’ve loved or lost was the same. If we all have the same vein? How strange a thought that if it were true. Would change everything I am and you?
