How could one describe liberation and or enlightenment unless one has a personal experience of it? There's no objective scholarly report from Enlightenment quarterly on what attainment of path and fruits feel like. What The Buddha has taught is the way leading to such a result. To your average practitioner of Theravada, that is what is important. Take care to cultivate the NEP and everything will eventually fall into place.
"For a disciple who has conviction in the Teacher's message & lives to penetrate it, what accords with the Dhamma is this:
'The Blessed One is the Teacher, I am a disciple. He is the one who knows, not I." -
