Everyone wants to be happy; happiness is a right. And while on a secondary level differences exist of nationality, faith, family background, social status and so on, more important is that on a human level we are the same. None of us wants to face problems, and yet we create them by stressing our differences. If we see each other just as fellow human beings, there'll be no basis for fighting or conflict between us.
We can change society, change humanity by changing ourselves as individuals. By cultivating inner values, we can change our own lives and those of our families. This is how we can create a more peaceful world.
