IMO cognitively we might find the "final" truth, but are unable to be fully enlightened until we are no longer hindered by physical bodies. It's obvious, to me, that everyone needs to keep seeking... especially those who think they don't need to.. imo ... How would we know what the "final" truth is, unless we have quit looking for any other truth.. that only means WE decided it was OUR final truth? There might be more truths out there to find!
