The link does not answer the question. The answer is: there is no enlightenment you're supposed to attain immediately after studying finite automata. You've created the possibility for enlightenment further down the road. Studying finite automata equips you with a bunch of knowledge about their behavior, which equips you with a bunch of knowledge about the behavior of a variety of other subjects, because they can be projected onto automata (can be reduced to automata, can be morphed into automata, ...). The link lists a bunch of properties of, and relations between, various kinds of FA's and explains how these are useful to other areas of CS and even to regular programming. But you cannot be expected to have these thoughts as sudden epiphanies. At most you can at a later time realize a certain property exists, realize the same property exists for FA's and realize that makes sense, because of the relation between your subject and FA's. You can then further realize that you know immediately know a lot more about the subject as well. Some of these realizations may strike you with a physically tingling sensation of aesthetically pleasantness which some call 'enlightenment', but YMMV.
