maybe the language here is what is causing a problem, maybe must
isnt the right word to use maybe does
so instead of one must spend eons
which seems to cause a bit of an uproar, we can say one spends eons
, which, i dont think anyone here (unless they're gonna go down the anti-rebirth route) will argue against, and i do believe there are sutta references out there to show we have wallowed in samsara for many lives, and sutta references to show that "because this is, that is" etc. so one could pretty much, if they wanted to, create a firm sutta based argument that in fact it does
take a long time, however it is a bit harder to say it must
take a long time.
