I'm curious, what exactly is your take on enlightenment?
the question is pretty broad.
i'll try just a few sentences and you tell me if that's enough
[i'm not saying that "enlightenment is like this, period". only that there is at least one person for who the following comments apply]
the state of enlightenment that i'm aware of is not linked to definitions coming from any religions
different people experience it differently
some people may reach it and then "loose" it
others may loose it but "remember" it; stay in this state; stay in between; be on constant progression to this state, etc.
so there are not only non-enlightened or enlightened / black or white states
there are all shades of grey and you can even go back to a former darker one even though you were progressing to white
it most likely comes in the form of an epiphany
but i see no reason why this epiphany could not appear over a long period of time
the insights of the epiphany may be too hard to explain with human language or even clearly comprehend with the human brain
it is life changing
except if you suppress the insights for various reasons (too hard to accept; still want to fit in; couldn't make sense out of them and think it was just a delirium; etc.)
an instance of insight, which has been reported by many others, is the realisation that we all/the whole universe/ share the same consiousness
i suppose that for many this comes with empathy and altruism
it helps you relativise many, if not all, matters
depending on "how enlightened" you are, you may not be bothered by any of your problems anymore, may not fear death anymore, reconsider the value of life
you may be able to deeply care for a cause without letting the suffering it produces prevent you from acting effectively to improve it
you feel at peace with yourself
don't feel lost
are confident.. just of being
may still yearn for more answers but not be frustrated by the lack of them
don't feel yourself as a human (or only partly) but as the whole universe
there is a feeling of awareness and understanding of the universe, even though it may not be possible to put it into human words

that was my take in a few sentences
for more, i'll need you to ask precise questions, thanks
