user7809: I think the title says it all.I know that an enlightened person's soul will go to nirvana after their death, but what is really nirvana? 
Is it some kind of a place or something like that?

user7049: it's definitely not a place, it's a no-place

user295: Nirvana is the cessation of the cause (attachment, hatred, delusion, non attachment, non hatred, non delusion) of continuous existance. With cessation of the cause perception and sensations cesses. The implication of perception cessing is of perception is you do not analyse any experience as good, bad or neutral and sensation cessing means the whole sphere of unsatisfactoriness cesses.
