enlightenment means that you no longer experience emotional pain as aversive.
Q. Would you care to sum up the purpose of meditation? A: Well, meditation is dealing with purpose itself. It is not that meditation is for something, but it is dealing with the aim. Generally we have a purpose for whatever we do: something is going to happen in the future, therefore what I am doing now is important — everything is related to that. But the whole idea of meditation is to develop an entirely different way of dealing with things, where you have no purpose at all. In fact, meditation is dealing with the question of whether or not there is such a thing as purpose. And when one learns a different way of dealing with the situation, one no longer has to have a purpose. One is not on the way to somewhere. Or rather, one is on the way and one is also at the destination at the same time. That is really what meditation is for. (Meditation in Action, p 83)
