Yes, it is possible to be in a position where you have to combine one card with itself. Most commonly, this special situation occurs frequently when you use the Houses system for reading Grand Tableaus.Any card can then be positioned in its own house. One way of dealing with this is to take the keywords of this card and combine the nouns with the adjectives, or to create the description of a situation by combining several keywords. Another (maybe just additonal) way is to put a lot of emphasis on the area of life the card addresses - the issues the card addresses are very strong or important in the querent's life. And a third way is to treat the identical twin combination as a >>Single Card Reading . I personally find this highly productive, but it requires you to be willing and able to view the cards more like Tarot Cards in this case, and interpret them as archetypes with multi-dimensional, elaborate meanings.
