I think we are all unique and are all unique expressions of a whole. An ocean is made up of drops of water that are individual and also part of the whole. Let's look at the grain of sand. It sits on the beach experiencing and the whole universe experiences its entirety through that grain of sand. We know the universe keeps expanding - why would it need to do this? Perhaps you can think of it as a repository of the experience of everything - imagine going into an ever expanding repository to look for the experience of that single grain of sand? The poem is William Blake , who knew a few things , like Carl Jung. Now Carl Jung said " I must hint at things that other people don't know or don't want to know". Does Carl Jung cease to exist? He is no longer walking the physical realm , but does everything he did while he was cease to exist? " Oh , we must take all his books out of the libraries - he doesn't exist anymore ! ' And it is a deep philosophy and not easy. We tend to focus on our physical body as being who we are and our existence. Its like a suitcase full of washing. We aren't the suitcase - we are the washing. And there's quite an industry for making the suitcase look good - if it has a nose / boob job it will be so much happier. It doesn't look as good as the other suitcases. But its the washing inside - the suitcase looks great but the washing is filthy. People do subscribe to the suitcase. Does anything ever get " lost "?. The universe puts out its building blocks of sperm and egg and experiences everything that comes from what grows - the child's first crayon strokes on a piece of paper , does anything ever get " lost " or cease to exist? The existential dillema is difficult.
