In the Tradition of Shūnyam there is no consoling advise proffered that you will ‘Live Forever’ [a thoroughly terrifying idea].
It is rather the issue of your claiming to have been ‘Born’ in the first place.
The summary sound-bite of organized religions runs: ‘Immortality is Eternal Life’.
From the ‘In Flesh’ extreme [‘All Day Golf’] to some abstract eternal residence as Spirit by the side of God in a perfected heaven. All religions by and large offer the same plans. You pick the company and policy you like.
At Shūnyam things get a mite confusing. It no longer is clear what ‘Death’ means if you can’t find the file documenting your ‘Birth’.
The Unborn [Ajatham]. The Unarisen [Abhutam].
You might find yourself ‘Immortal’ in spite of yourself.
The venerable Japanese Zen-Master Hakuin, at his moment of Satori: ‘How wondrous! How wondrous! There is no Birth and Death from which one has to escape; nor is there any supreme knowledge [Bodhi] after which one has to strive…all the complications [Koans] numbering 1700 are not worth the trouble of even describing.’
