Tarot spreads
A spread is a set of positions, and each position asks the card a different question. The same card means one thing in a position about the past and another in a position about what is standing in your way.
That is the entire mechanism, and it is why more cards is not better. A single card answered clearly beats ten cards you cannot hold in your head at once.
1 cards. Numbers show the order they are dealt. Single Card
One card, quick clarity
3 cards. Numbers show the order they are dealt. Three Card
Past, present, and future
5 cards. Numbers show the order they are dealt. Relationship
You, them, and what lives between
7 cards. Numbers show the order they are dealt. Horseshoe
Seven cards arcing from past to outcome
10 cards. Numbers show the order they are dealt. Celtic Cross
The classic deep dive — 10 cards for full clarity
If you are starting out, use the three card spread until it feels boring. It teaches the thing that actually matters, which is reading cards in relation to each other rather than one at a time.
