It means that level of thoughts of the people of the world develops in the way that they understand the issue “race” and “different geographical regions” are not considerable issues in human life; the differences of colors, languages and lands cannot separate humans from each other; tribal and group fanaticisms should die forever; hilarious thought of “superior race” should be thrown away; factitious borders with barbed wires! And wall like the ancient wall of china! cannot separated humans.
But, as sunlight and lively breezes, and raining clouds and other gifts and powers of the nature never pay attention to these borders and all of them move around the entire earth and practically consider the world as one country, we humans also reach this level of intellectual growth.
And if we carefully notice then we see that this thinking way is going to be created and completed among aware and open-minded the people of the world, and day by day the number of those who think about the issue of “world-country” is increasing.
Even today, the matter of united global language is being discussed in different places.
