National Integration: - As residents / subject of one nation, we have to live happily for which safety is required. If every one of the people honours others like himself, all will be on equal plain. This will create sense of confidence in each other. When one thinks that all the people are like myself, he never dares to harm any one. This will bring safety and people will be united by body and mind as well. To be united by body and mind to each other is intigration. When thought of all nation, it is national integration.
International understanding: When think of our national integration, there are so many nations in this world and if people of each nation think likewise, none of the nation will harm the other for any reason. They will understand each other properly. We cannot choose our neighbour. Who ever is sent or fixed by the Suprimo of the world we have to accept him as he is and live with him without disturbing our as well his national integration. This is principle of peaceful co-existence.
When National and International integrations are achieved properly by understanding each other on individual as well as national level, integration between the two is automatically achieved.
