Time is actually not linear, its cyclic

Time is actually not linear, its cyclic.
Which means if death is inevitable, life too is inevitable. Means once some one die, its has to take birth again. And may be Nirvana is not freedom from this cycle, Nirvana is just knowing this knowledge from the core of our existence. And yes it quite possible that after knowing this knowledge, we can choose/alter/plan our birth, but it's inescapable to not to choose. Nothing is out of cycle, its natural axiom about the time.
