[ETA: Oh, and thank you for clarifying that for me. That was most helpful.]
Hey! Congratulations! What a fun journey you’re about to embark upon.
Don’t worry about being a total novice or that this is your first deck (I like the positive expectation that you built into that idea for yourself!). Sammy’s got you covered. Check out his thread, created just for you: Beginner’s Journey through the Corpus Spiritus Tarot. It’s only just begun, so you’re joining in at the perfect time.
Well, yes, that’d be fun, and that’s the key: that this be fun for you. This meditation or sitting doesn’t HAVE TO be something hard or an arduous task. Legend has it that the Tarot was designed as a game and I think that’s the best (certainly, the funnest) attitude with which to play with them. Approach your cards as a fun adventure where you get to explore, but from the comfort of your home. Just look at the cards and see what catches your eye and what sparks your imagination. You don’t even have to DO anything. Just relax and let your imagination do the rest.
And, as @MonkeyOwl points out, you’re not going it alone. You can always go online for suggestions. And most modern readers started out that way. Heck, I think most commercial decks being published now come with some little booklet of meanings to get you started. So, there’s nothing wrong with (and I’m being playful here) “cheating” a little bit, you know what I mean?
That being said, if I may be so bold, I think the reason why you might have gotten this deck is because you’d like a connection with this deck. And that comes from the playing with it that I’ve described above. If you had just wanted to look things up on the web, I think you would’ve been satisfied with an even more affordable, mass produced deck, if you know what I mean.
