"We are all connected to each other biologically, to the earth chemically and to the rest of the universe atomically.
That’s kinda cool! That makes me smile and I actually feel quite large at the end of that.
It’s not that we are better than the universe, we are part of the universe. We are in the universe and the universe is in us."
