Jai Sri Ganesha,
Happiness is a chapter which relates on the subject which differ from person to person,
It is a state of mind that in conformable zone with self,
Eternally it peace alone that lead self to its inherent truth which indicate respective joy,
Worldly happiness are short liven and diluted itself with its initiation, but eternal joy once reached at is different than transitory truth,
May Lord bless all,
Thanks please
