I got it from a book I'm reading, Lon Milo DuQuette's Understanding Aleister Crowley's Thoth Tarot. although this exercise could be done with almost any deck.
DuQuette describes how each trump card, (major arcana), is a world unto itself. And each trump card rules over each the 56-cards of the minor arcana.
When a trump card is next to a minor, it exudes an influence over that card which you can learn to recognise and interpret in readings.
Crowley gave this example of how the 3 of disks (Work) can be read when it lays next to:
- The High Priestess or Lovers cards : The establishment of an oracle like that of delphi
- The Hierophant: it might point to the construction of a cathedral
- The Tower: the massing of a standing army
You see how he looks at what each individual trump card might want to "work" on.
Okay, Crowley tended a bit toward drama. We don't run into many Cathedral building projects or much standing army organising, but you could easily bring these concepts into something relevant for your reading.
For example, someone is feeling spiritually low, the Hierophant and 3 of disks might be saying the person should set up a little alter or create some kind of sacred space for themselves to re-charge.
Or someone has a project that is becoming too big and you draw the Tower and 3 of disks. Maybe it's time to build a team to tackle it.
If you want to practice this, you could take all the Majors out of a deck, then select one Minor to pair each major with, one-by-one and write down your answers. You will get a feeling for this kind of combining while learning more about each card.
Just for fun, you could try pairing the 3 of disks with one or more of the following cards and in a reply to this thread, share what you got.
Or use any cards you like. These are just to make it easy to try it out here.
Maybe we could turn this exercise into a kind of "workshop" thread, and do it together somehow.
But for now, I'd encourage you all (especially beginners) to have a go at some "Pairing and Sharing" and see what we turns up. In any case it's good practice with the cards and could be a very helpful skill to have in readings on down the road.
