Q. What according to u is the happies state in life? Include what one must have to be happy and also what one shouldn't have?

In our world all are not happy. A person is sometime happy and other time very sad. The same happens in our life. If my father or my mother or my teacher or anybody shouted at me , am very sad.When I get first rank in the class, we will go out on weekend for celebration.That time I am very happy. In my country there is no earthquakes , but in other countries there are earthquakes and bomb explotions which make people sad. I pray to GOd all time that all must be happy always.

Thanks
