The notion of a rising sun is a misnomer. The sun itself does not rise or set. If I am on the east coast of Australia and see the sun rising over the Pacific Ocean, it is the same sun a person in the United States would see at midday. The difference between my “rising sun” and that observed by my American cousins depends solely on the location on the surface of the planet on which we stand. To an observer out in space, looking at our pale blue planet, the concept of a rising sun is absurd; it is rooted in our past when we believed we were the centre of the universe.
Nationalism is like this; it only exists when we allow our perception to be limited by our location. If we let go of this outdated notion, our minds can break free from their terrestrial bonds, allowing us to focus on solving the real issues of our time.
