This world is not our property!

You do not belong to this world. The world is an illusion. Our physical world is not the reality, infact, we are far away from the reality. And I think, right and wrong are also illusion because it never existed in spiritual world. I mean think that you are on another planet and there's nobody, you are alone there. You know you have to live there and that's the oy choice, otherwise you will die. Obviously, you will live there. It's not the person but the place that decides whether you are right and wrong. No, actually clarify me, how a single person in an unknown place, alone there can be right or wrong???
