Most early Tarot books said you needed to memorize all the meanings before you tried to read the cards. With the RWS deck people began to simply project stories onto it (whether psychological or psychic). A few people are able to do that with playing cards. Modern Tarot teaches that we can just go with the symbolism. Certainly you can use Lenormand cards as an intuitive, symbolic or projective Oracle device (Bear mythology says . . .). But you aren't really reading Lenormand, since it is more of a system as well as a deck.
[You can also read Tarot according to a system, if you choose to do so. The original Golden Dawn Tarot system, for instance, is very specific.]
Once you learn the system you can go with your gut reaction or intuition, but it's what I call an "educated intuition" in which you used the Lenormand system "rules of thumb" to increase your accuracy and be more specific.
An example, in another field: I might "intuit" that you are ill. A trained medical intuitive might see an image symbolizing the problem (a train-wreck in the left . . .). A medical doctor might intuit something far more specific that guides which tests she orders first. [My doctor said we could do a whole range of expensive allergy tests, but suggested I first go off all dairy and see what happened. All my severe allergic reactions disappeared. Why dairy instead of gluten and why not the systemic poison oak that all my "intuitive" friends had said was the cause?]
