What Is Tarot
Tarot is a system of images and symbols built up over several centuries, with no magic in it. It is good at helping people see their situation clearly, and it leaves the decision to them.
Why tarot seems to "work"
Tarot cards have no supernatural power of their own, and they don't belong to any particular religion or to either side of good and evil. They are a system of images and symbols. Whether a reading is accurate depends on the reader's skill and experience; there is no built-in "spirit" in the cards that makes it so. As for why the cards drawn so often match the querent's situation, the common explanations mostly come from psychology, and there is one more that comes from anthropology and the history of ideas:
- The collective unconscious and archetypes: Jung proposed that, beyond the consciousness formed by personal experience, people share an inherited layer that doesn't depend on individual history. He called it the collective unconscious. It is made up of archetypes, and it shapes judgments and choices without our noticing. Readers who favor this explanation hold that drawing cards lets this layer "project" itself through the images, so the cards can show a situation the querent may not even be aware of.
- Synchronicity: Also a concept from Jung. It describes two events with no causal link that still echo each other in meaning. When what the querent has in mind lines up with the card that comes up, this is read as a "meaningful coincidence" rather than cause and effect.
- Correspondence thinking: Rachel Pollack offers a different framework, drawn from anthropology and the history of ideas. In her view, divination rests on a much older worldview. Many traditional cultures understood things through correspondence rather than causation: the movement of the stars corresponds to the course of a person's fate, the pattern of tea leaves at the bottom of a cup corresponds to the outcome of a battle, and everything in the world is connected, so nothing is purely isolated or meaningless. Calling something "random" is itself a fairly recent, modern habit of mind. It rests on the premise that only causal links count as real connections, so any correspondence without a causal chain gets filed as coincidence, noise or superstition. Whether tarot divination holds up depends, in a sense, on whether the reader is willing to look at the echo between card and situation through correspondence thinking. Whether a causal chain between the two can be proved matters much less. Western occultism has its own version of this idea. The Golden Dawn called itself the Hermetic Order of the Golden Dawn, and one of its theoretical roots, the principle of correspondence ("as above, so below"), expresses the same worldview: the laws behind small things mirror the laws of the cosmos. This is also the philosophical basis for the correspondences that link astrology, the Kabbalah and tarot; see How Tarot Became Occult inferred.
- A common objection to the "unconscious projection" idea: OH Cards, a set of projective cards used in counseling, are accepted as a legitimate psychological tool because the user actively picks, from cards laid face up, the one that relates to their situation. The path of projection is plain to see. Tarot cards are usually drawn blind, so there is no direct way to show that the unconscious "guided" the choice of a particular card, unless you also assume the unconscious has some extraordinary perceptive power, and that assumption can't be proved either. This is why psychologists generally don't accept psychological theory as an explanation for tarot.
Each of these explanations is internally consistent, but each uses one unproven theory to explain another unproven phenomenon. None of them amounts to proof in the scientific sense inferred.
If you accept an explanation like the collective unconscious or synchronicity, the practical advice that follows is: relax when you draw, keep your mind clear, and don't fixate on getting a particular result. Otherwise what comes up is more likely a projection of what you consciously want than the message the unconscious or synchronicity is trying to convey.
If anything can be used for divination (and historically almost everything has been: animal entrails, the flight of birds, stones, coins), why use tarot in particular? Pollack's answer is that any divination system will produce patterns people can "read something into." Whether what they read has value and depth depends on how much wisdom the system itself has accumulated. The mystery of the act of divining has little to do with it. Tarot has been handed down for several centuries, and generations of artists have refined its images and filled them with symbolic meaning. That is what lets the cards, in combination, offer weighty insight into the querent's situation and even their life as a whole, which you would not get from any object picked up at random inferred.
What tarot can help with, and its limits
A solid reading can usually help in several ways: it shows the real challenges and obstacles of the moment; it adds a little push toward getting out of a difficult spot; it turns a vague short-term goal into a concrete next step; it clarifies a long-term direction that is still unclear; and it points out pitfalls to avoid right now. What these have in common is that tarot helps the querent see clearly, while the decision stays with them. Querents expect very different things from tarot. Some hope the cards will announce "the name and birthday of my future partner," and others simply want someone to listen while they talk things through; both are common. A more mature approach is to treat tarot the way you would treat a consultation with any expert: come with a question, hear one perspective, make up your own mind, and stay aware throughout that you have free will. You can accept the direction the cards point to, or you can change it through resolve and action.
The limits deserve just as clear a statement. First, any prediction is only "a slice of the present." It reflects the situation and energy at the moment of the draw, and the future it describes is not fixed. Even when the reader has the best intentions, the analysis can be wrong. A common reason is that the querent is in the middle of an emotional storm (just after a major upheaval, or at a moment of extreme turmoil). In that state, a strong craving for a particular outcome can itself sway which cards are drawn and how they are read. The more responsible course is to suggest waiting a while before doing a reading; see Reading Tarot Professionally.
Second, tarot is a poor fit as an oracle to consult before every decision. Early in learning, it is easy to want to ask the cards about everything, large and small. Doing that puts a brief draw above the judgment that should be your own, and it also makes it more likely you'll ask questions without much meaning and get answers with just as little. A sounder approach is to first work out the background of a matter and your options yourself, narrow them down to the few choices that are truly hard to decide between, and then ask the cards. At that point the reading is far more useful.
