Man cannot live alone. So, man lives collectively in a big family known as society. A well knitted society needs good understanding and cooperation among its members and it can be achieved if each member is sincere about his own responsibilities and acts accordingly. On the contrary, if the members are only self-centred and are least interested in the welfare of the society, the society soon becomes a hell. So, be dutiful towards the society where you live and will have to live always.
