I believe that if we make an effort to develop peace of mind within ourselves and cultivate a proper appreciation of the oneness of humanity, we can create a happier, more peaceful world. What we need is common sense—the positive use of intelligence—and warm-heartedness.
Wherever I go I consider whoever I meet to be another human being like me. We all want to live a happy life. We all respond to smiles, so wherever I go, I smile. Even when we don't share a language, we can communicate our friendship by smiling.
