How is our presence not a part of the universe?

Even when we are physically no longer there, our presence, once manifest, cannot ever be undone - it echoes through the future into eternity. So also does it echo into the past, in all those moments that lead to our manifestation in an unbroken chain throughout time and space.

We are inseparable from the universe, and the universe is quite literally inseparable from us. We are the universe.
