Its all in our mind.....

I always wonder what if there were no countries, no continents, no religion, no caste, no race, would earth be a better place to live or would there still be chaos just like it is today??? I guess there will be because all the mess that we see is not because of these differences but because of the feeling of being superior in our minds. And this is still gonna be there coz its human nature to look down upon others. Till the time this doesn't change there is always gonna be hell on Earth. It's our mind that needs to change. We need to start living our own life instead of interfering in others and should stop criticising others.
