Where the so-called problem of 'death' is concerned it would seem reasonable to start by enquiring 'What is there to die?'
One obvious answer might be 'Whatever was born'. Another should perhaps be 'Only what is called "matter" can be subject to either birth or death'. Thus these answers are inseparable.
'Death' and 'birth' are inseparable also; that is to say they are only apparently separated as a consequence of the conceptual extension of the concept of 'matter' in space and duration.* But that, absolutely all that, is ideation.
Apart from ideation, what could there be to be born or to die? The living-dream and the dying-dream are not essentially different from the sleeping-dream - since all are ideation in mind. 'Waking' and 'sleeping' are a pair of relative and interdependent counterparts, inseparable and only negatively veridical - veridical in mutual negation.
* 'The cause, displaced in time and space, appears as its effect.' (The Nirvana Prakarna of the Maha Ramayana). Death, therefore, appears as a space-time effect of birth.
