It’s the act of asking: That’s what makes a reading work.

The medium helps, but you get an answer because you’ve asked a question (explicit or implied)

You’ve ‘cast out the middleman’ and selected a method for your communication. It doesn’t matter if it’s Tarot, Lenormand, ordinary playing cards, or a system you’ve made up on the spot; the divine will try to answer using the tool you’ve made available.
