"And there is no new country, friend, no new sea; Because the city will go with you all the time," highlights that no matter where you go, you carry the city within you. It suggests a sense of entrapment, where wandering leads to a repetition of the same streets and dreams, making the city feel like a prison from which escape is impossible. The city's presence persists in every place, and your identity remains tied to it, disallowing true freedom or escape.
"Foollings, you still misunderstood that as you missed your life here on this piece of the world is just as wasted Even everywhere else - on the whole wide country?" emphasizes the idea that searching for fulfillment elsewhere is futile because the true limitation resides within oneself. No matter where you are—whether in your current city or exploring new lands—the same internal barriers and feelings of entrapment may persist, making genuine escape and happiness elusive.
