I would like to have picked something other than "Meaning of Topic Unclear" but it's hard to, because if we're meant to be literal then what is the "re" in "rebirth" referring to?
The prefix "re" is "used with the meaning “again” or “again and again” to indicate repetition, or with the meaning “back” or “backward” to indicate withdrawal or backward motion: regenerate; refurbish; retype; retrace; revert".
In this context does it mean something is happening over and over again, or that something is being born over and over again? And what is that "something"? And if the "something" occurs again, is it the same as it was, and if not, what basis do we have for stating it was "re" born?
The answers to such questions would need to be clearly specified before I could give an answer... and depending on how it was specified I could probably select any of the above poll options, so I'm not just being difficult despite what someone is bound to think.
Either way, it's not a subject I'm particularly obsessed by, because I haven't invested heavily in the notion of future lives (i.e. intentionally postponing enlightenment so as to ferry all beings across to the other shore). What is good now is good for the future, whatever that may be.
beeblebrox touches on some good points above.
