I'm not enlightened, but I think that focusing on it is probably counter-productive.
I like Shunryu Suzuki's attitude... which is to focus on practice and not worry so much about enlightenment.
I think enlightenment is when you get it on a very deep level that many things are simply just a matter of perception, and that, perhaps, you perceive some kind of objective truth that doesn't leave you.
So, when you're enlightened, it doesn't become such an effort to see things more as they really are and less shaded by past history and other filters that distort information coming through your senses.
Enlightenment, though, may not be truth but may be just a better, more functional illusion than the one you had before enlightenment.
I don't know, however, because I've never been there. I've had moments that I consider enlightening.... but they haven't led to enlightenment as a permanent or semi-permanent state.
