The Minor Arcana

Fifty-six cards in four suits. If the Major Arcana describe the chapters, these describe the days: the argument, the invoice, the idea you had in the shower, the friend who keeps not calling back.

Each suit owns a domain. Cups feel, Pentacles build, Swords think, Wands want. Learning which suit dominates a spread tells you what kind of problem you are actually looking at, often before you read a single card.
