Nature, body, mind go to death, not we. We neither go nor come. The man Vivekananda is in nature, is born and dies. But the Self we see as Vivekananda is never born and never dies. It is the eternal and unchangeable Reality.
We are afraid of losing what we have, whether it's our life or our possessions and property. But this fear evaporates when we understand that our life stories and the history of the world were written by the same hand.
