Must read…Camoin basic rules for reading TDM…
The method works for me, but…his claim ‘heir to a tradition which goes back for many centuries’ is contested in the Tarot community.
1st rule :
It is always the person asking the question who shuffles the cards and selects the cards. The cards are placed face down, and it is the Tarot reader who turns them face up at the appropriate time.
2nd rule :
When a card is in reverse position (of course from the perspective of the querent) it means that the energies of that card are blocked. If there is not already a card directly above (or below when following a variant method – see Upward and Downward Spreads) the reversed card, another card is drawn and placed there. The new card is always placed upright. It indicates the solution, the direction to take, what needs to be done to remove the blockage of the reversed card below it. It is the card that “cures” the reversed card.
3rd rule :
When a figure in the card gazes, or “regards”, in a direction where no card has been placed, another card is drawn and placed next to the first in the direction of its Regard. This card can be either upright or reversed. For instance, if the Pope is upright in the future position and it is looking at an empty space without a card, another card must be drawn to see what the Pope is regarding. This new card can be either upright or reversed.
4th rule :
When a similar symbol appears two or more times in the spread, it is important to pay attention to that symbol. For instance, in The Empress, The Emperor and The World, an eagle appears three times.
5th rule :
When the problem related to the blockage in a reversed card is resolved through the Tarot reading, and/or in dialogue with the querent, the reversed card can be placed upright. The situation thus transforms and the new reading appears which corresponds to what is occurring now that the problem has been remedied.
6th rule :
When all the cards have been placed and there are no more cards to draw, the spread is in principle finished. However, it is possible to continue to read the cards in the spread in relationship to information that surfaces during the discussion. For example, a certain card might represent a member of the querent’s family, a work colleague, or another person related to the question. Another reading can be made based on the card representing the particular person The new reading will give an idea about the life and surroundings of that person. 7th rule : Variations are of course possible using the Minor Arcana or with other structures than the standard spread beginning with three cards; for example, the Cross spread, spreads with more cards in a row horizontally, or any other spread. 8th rule : When using the Minor Arcana, the rules expressed above equally apply, in particular those on the direction of the Regard for the figures in the court cards: Page, Queen, King, Knight.
