There are different degrees of enlightenment. Generally after
deep insights you will have increasing dispassion. You notice your
afflictions lessen and no longer arise much. But as for complete
dispassion, only arahants are completely without passions.
Experience becomes direct, immediate, gapless, vivid, releasing,
blissful, etc. Experiencing without imputing 'I' and 'mine' is very
liberating indeed.
Imagine carrying a 20kg load for 20km and putting it down.
When you are able to fearlessly release, open up and embrace all
dharmas that manifest via dependent origination without an embracer
and without a trace of self, it is blissful and
liberating.
