Most people come to the cards with a question shaped like a forecast: will this happen, should I do that, what is coming. The cards are very bad at answering those questions, and pretending otherwise is where most readings go wrong.
What the cards are good at is description. Not of the future, which is not in them, but of the present — the pattern you are already standing inside, usually without having named it. A reading done well does not tell you what will happen. It tells you, more precisely than you had let yourself see, what is already happening, and what postures are available to you within it.
The shift is small and total. You stop asking the deck to decide and start asking it to describe. The question changes from what will I get to what am I in. From there the work is yours: the cards have returned the situation to you, more honestly framed, and left the choosing where it always belonged.
