Well, I'll take a stab at this, and then you'll get a bunch of responses from folks who will tell you all the ways I'm wrong!
It is my special talent.
As you know Tarot cards follow a very specific format and historic set of "rules". We modern people have started to play around more with Tarot and are changing things a bit, hence the endless discussions about what makes a Tarot deck a Tarot deck. Basically, 78 cards, four suits of cups, wands, pentacles and swords, four courts for each suit and then of course the remaining cards are the majors.
Oracles historically have been places, shrines or temples, where a wise woman or man gave out cryptic statements...example the Oracle at Delphi. Nowadays, many people are creating oracle decks, all kinds of them, and the decks cover all kinds of topics and styles. They have fewer rules than Tarot decks, and they are used by people for different things.
I use some oracle decks quite often and love them. My favorite is the Froud Faeries Deck. It is beautiful and I just layout cards like I do Tarot and read them intuitively.
Now with Tarot, many people give the cards meanings. So there is a common ground and language spoken around it. RWCS readers will all agree, more or less, that the Six of Cups talks about some kind of nostalgia, remembrance, youth, even birth of a baby. And so on.
With Oracles, there may be less consensus. There is room built into the Oracle for independent thinking or intuition. A little less rigidity, but I'm already thinking of a few Oracle decks that bust that statement!!!
Anyway, just get your Oracle and read it intuitively. Go with what comes to mind. Explore your symbol set, what you believe things mean.
Because whether it be Tarot or an Oracle, if you see a white dove, and the books says, "Peace, brotherhood, purity, innocence", but all you see is "chaos, disruption, turmoil" well then, why trick your mind into believing the first set of defintions? you gotta go with what is in your gutt.
Good luck!
