I think you should read the books on Zen by Alan Watts.
Well, the re-writing of Zen texts in a way that is understandable to a western mind, by Alan Watts.
Enlightenment in the context the thread started out with is the buddhist/hinduist ridding oneself of the fruitless desires and unnecessary sufferings of this existence, gradually moving towards our true 'buddha' nature - Nirvana/Nibhana.

Thats where I started out, you'll probably progress to a few other of Watts' works before plucking up the gumption to head into D.T. Suzuki's works.
I'd check the libraries out. If they have anything on buddhism, they should have some of Alan Watts'and D.T. Suzuki's work.
Well, if you're still interested.
