I always open the box, pick the deck and slowly "bath" each one of the cards in stick incense smoke - away from the stick, generally way above the censer. No one wants burned tarot cards to read. As I do this, I look at the images and get to know better the archetypical characters, symbols, stories told, situations suggested by the cards, suits, groups. Shuffling the deck and talking to it usually follows.
I balanced my first contact to be imaginative and structured with my Ancient Tarot of Marseilles and my RWS. I always started a kind of dialogue with each trump and court card. In a card like the Tower, I would face the event and talk to the people that fell out. Even if my imagination did not go this far sometimes, I took my time with each card, thinking of all its meanings, messages, particularities, manners. It was like a well oriented ritual. This second variant of the method was unavoidable with the pips. I only studied the Marseilles pips much later.
With my Crystal and Old English Tarot decks, I became more of a dreamer, making up stories without needing to thoroughly study all cards. The CT was like a visit to a colorful, beautiful world of healing balms. Even the Devil is kind of a cute guy in this one (despite that mean upside-down pentagram on his head)! As with those crystals very unharmonically thrown in the cards, maybe a crystal study will do some good... Anyway, OET was like entering a very stern but exciting world, real and historic, with christian lore peppered with pagan little things. Love my decks.
