"Talking Through the Tarot
The Tarot is a willing and effective medium for spirit communication, as it expresses itself through a universal language of the soul that speaks to both the dead and the living.
Once you've laid down proper protection, you may want to sit out food, drink, and lit candles as an invitation to the dead. Begin by shuffling your deck and asking the spirit or spirits to join you for a friendly chat. If your invitation is accepted, you will feel a presence and you will know that your fellows are with you. Candles will flicker and the air might grow a shade colder. You might even feel light touches on your head, back, arms, neck, or shoulders.
You can now talk to the dead and ask questions, inviting them to answer through the Tarot. For example, you might pose the question, "How are you?" You would then mix the cards and allow your fingertips to be spiritually directed, selecting the card or cards you feel most drawn to.
The cards chosen express the spirit's answer or message, and you should decipher the meaning with intuition, a good memory, and an open heart. Sometimes, the traditional interpretation of the card is conveyed, while other times, the symbolism might speak of something specific to you and your dead pal, an inside joke of sorts. For instance, the Ace of Cups can mean that the spirit is in a state of peace, bliss, and wholeness. Alternatively, it could refer to a special time when you and the deceased shared a glass of wine, and could mean that the spirit misses the good experiences you shared.
You can also use the Tarot in the other direction, to express your ideas to the dead. For instance, if you want the spirit to know that your children are well, place The Sun card beside the Ten of Pentacles or another happy arcanum. Likewise, to ask the spirit for protection, you could set out the Ace or King of Pentacles; to ask for good luck, the Wheel of Fortune is a suitable choice.
Talking to the dead through the Tarot can be an intricate or a simple procedure. You can use the cards to just say "Hi," or you can use them to obtain extensive and detailed information. You may feel like picking just a card or two to check in and be done with it, or you might be led to lay out the cards in a complete reading such as the Celtic Cross. Your need to know and the spirit's willingness to communicate will shape the conversation, so just let yourself be guided."
