It is hard to have a truly "united" world, but whatever the differences, people must show each other respect. 10 years ago, individuals showed no respect and heart and had to do something that goes against everything that the majority of the world's population believe in.
Peace is never easy, peace does not start by writing up agreements or merely shaking hands in front of cameras. Peace is the Way of Mind.
If we are peaceful within, peace will radiate from that individual to other individuals.
I hope that we all individually stay humble and peaceful within ourselves and allow our example to be radiated across nations.
