I believe that's what was meant. There are several books out there about using tarot cards for magic rituals as well as for spells. I have done both, using combinations of cards that symbolize what it is I'm having issues with and what I want done. Again be very careful, you have to be really precise.
I wish I could suggest a book to you off the top of my head. Either go to a Half Price Books, Barne's in Nobles or other store and browse (beware of gimmicky stuff)! or just figure out your own way of doing it. I suggest the latter.
