What is being discussed here, Lollo? There's nothing wrong with enlightenment in some contexts, but in many others (perhaps most others), inspired is fine, too. It sounds fine to me as far as I can tell, but a little more context will help us understand what you're confused about.
Both get inspired and get enlightenment would fit in here (though enlightenment would be a more unusual choice). The choice of which to use comes down to the writer, and here he apparently decided to emphasize inspiration instead of enlightenment.
