We can cure physical diesases with medicine, but the only cure for loneliness, despair, and hopelessness is love. There are many in the world who are dying for a piece of bread, but there are many more dying for a little love
Like Mother Terasa had said once there are millions who die without food but there are millions more who die who dont get love. I am sure if each and every person gets their share of love this word will not exist other than in dictionary.
RE: sadness...
Very nice. Like Martin luther King and Gandhi said Rule over self as everyones life is an message
