Dear sister, you are only fourteen, you should be thinking and concentrating about your school work and respecting your parents and not be worried about some mumbo jumbo about heavens. Heaven and Hell is all here, we don't have to wander far to search. Soon as we forget father allmighty lord we enter hell. It is that simple. The enlightend ones experience Heaven every where all the time. The culprits burn in Hell. All this is the play of Waheguru, only few understand this. So concentrate on your simran day and night, and don't worry about christian heavens.
