One of the most important things in a nation or a group of people is the art of communicating. Language does not only refer to words itself. But it envelops and includes your feelings which you would want to deliver. When everyone is inline in a harmonious language, surely there will be peace. But if the exact opposite happens, then the lives of the people in that particular nation or place would feel miserable. And that is why I personally think and agree that Language is the soul of the nation. Let us all, even though difficult, try to achieve and set this as our goal. Because everything starts within us.
