Lal,
I was asking for Tipitaka reference that a being’s stay in sansara can last forever – i.e, that it may be that Nibbana is never attained, despite an eternity of time in the future to attain It:
-“Is it inevitable that a being eventually attains Nibbana? Or can some or many or most – I do not know- linger on in sansara indefinitely? “- ….and following.
I of course refute the opening quotation; it only leads to the question via connection.
thank you
