You know your inside, and you know the others' outside: that creates jealousy. They know your outside, and they know their inside: that creates jealousy. Nobody else knows your inside. There you know you are nothing, worthless. And the others on the outside look so smiling. Their smiles may be phony, but how can you know that they are phony? Maybe their hearts are also smiling. You know your smile is phony, because your heart is not smiling at all, it may be crying and weeping. - Rajneesh
