As mentioned previously Tarot divination traditionally used geometric layouts rather than linear ones. A simple linear reading moves either left or right of the cards drawn. Geometric forms like pyramids, stars and crosses add dimension by giving height and depth i.e. a below and above and in some layouts provide a diagonal path which gives a fuller view of the situation or the person being divined for.
The simple 3 card pyramid layout is great for relationship and comparison reads, as is the hexagram. The 5 card pentagram is a very basic layout and shows the elements as energies in a situation.
When the cards are considered as energy holders then the energies activated by the shuffle flow into the geometric design and reveal a message. Readers from a Hermetic background often use the Tree of Life as a layout. ToL is a composite diagram which contains the forms of pyramid, cross and diagonal lines. A card is placed in each position of the sephirah.
In using the Marseilles Tarot all 78 cards Trumps, Courts and Pips are put into play when using the layouts shown and mentioned here. Each position in a layout has a fixed meaning in the forms we have covered above. However, more cards do not a better reading make. A masterful reader can answer a query with just one Tarot card.
