Hello Gazou,
I'm picking up on your last paragraph:
So you're saying, for example, that if you ask a specific question, there's a risk that you'll interpret the answer in relation to your wish rather than in relation to the readings?
Yes, and it is also true that our wishes arise in relation to the question. A negative situation that concerns us may come to light, but we do not receive an answer as to what might happen in the future with regard to that situation.
Even if the reading can reveal a reality, it is the sometimes erroneous interpretation that we will take into consideration, completely diverting us from the conclusions that would have been useful to consider.
Sometimes we pull the same cards for the same question through multiple readings; whether the cards are good or bad, if our interpretation is skewed when it comes to ourselves, it can lead to a dependency that brings about depression, because what we believe ourselves to be is ultimately something entirely different if the cards had been interpreted correctly.
