So as a scientist, I take a very pragmatic view of the cards. My take is that the tarot represent human experience in 78 cards, and if you're well-studied, each one has multiple aspects of the card that may be more or less relevant for a specific reading (that is, there are different ways you may interpret the same card depending on the question that was asked, or how they interact with the cards around them). That's not to say that a good reader is making things up or "picking and choosing" persay, but more that the cards represent complex ideas. So in the same way that I as a person really enjoy hiking, I am also a person who currently has a cast on (so hiking isn't relevant for me today). Each card has wisdom to share, so no matter what cards you draw, it will hopefully be helpful. The questions asked, the situation in the life of the querant and the skill of the tarot reader will determine what exact wisdom is there and how helpful it ends up being. So even though I believe that each card has widsom and it doesn't matter what cards are drawn, persay, there have been studies done (by physicists Jane English, PhD and Brian McCusker) that show that drawing cards from a deck of 78 blank cards (numbered but otherwise blank) will yield a statistically random collection of drawings. In contrast, drawings are not random (in that some cards are drawn more or less often than you would expect in a random drawing)for tarot cards. I have no idea what's up with that. As far as helping someone to become "in tune with their energy," I think some people might frame it that way. If that works for them, awesome! I don't disagree with that description but I think a way I am more comfortable stating it is that a tarot reading can be helpful as a means for self-reflection and intentionality in one's life.
