If you are really feeling happy, you are feeling happy even if the whole world contradicts you. If the whole world agrees that you are not happy, then too it doesn't matter. Your happiness is real. It cannot be canceled by anybody's opinion. But if your happiness is unreal, it can be canceled by anybody. Even a small child can cancel it. You will be constantly looking towards people. You will be smiling, trying to show that you are happy so that they can say, 'Yes. You are very happy. You look very happy.'
