I generally sit in a comfortable chair at my table of which I put a cloth over. I dim the room, sometimes I use candlelight, but that isn't always necessary. What is necessary is quite. I put the deck (I use the pathfinder deck) in front of me on the table and I place my hand on it. I close my eyes and focus on all the good energy around me and I draw from it. I pick up the deck still eyes closed and shuffle by feel alone, letting the energy conduct me. When I feel I have been guided to the right shuffle, I deal out the cards, usually in the Celtic Cross formation. I flip and read the cards. I'm a conduit to the energy. Once the reading is done. I put the cards back on the deck, send my excess energy back, and put the deck as it is in the box until I use it again.
I find Tarot is not something you can or should force. You let the energy flow through you and the cards speak to you. It's quite exhilarating.
If I read for you, I will tell you what cards I drew.
