" Recently I was sitting with a group of children, and a boy named Tim was smiling beautifully. I said, “Tim, you have a very beautiful smile,” and he said, “Thank you.” I told him, “You don’t have to thank me, I have to thank you. Because of your smile, you make life more beautiful. Instead of saying, ‘Thank you,’ you could say, ‘You’re welcome.’ ” If a child smiles, if an adult smiles, that is very important. If in our daily life we can smile, if we can be peaceful and happy, not only we, but everyone will profit from it. This is the most basic kind of peace work. When I see Tim smiling, I am so happy. If he is aware that he is making other people happy, he can say, “You’re welcome. "
