It's the first card. Number 0. When you use tarot (or other ways to confirm what you alredy acktualy know. Befor your logick mess it up. ) it helps if you have made up what ech card (or other thing you use. ) means to you. Also it helps to have a understanding on how the first arcane in the tarot deck work. (if I don't remember wronge. It's 3 lines, with 7 cards in ech. Can't remember if the fool is the card, that ends outside or not. But it ends with the world. If I don't remember wrong. )
maybe the that's what the cards are trying to tell you?
And allways remember. To read about what the difrent cards mean. It helps. But in the end. When you use the cards. It's what they mean to you that counts.
Well. That's a bitt about how I use and understands it tho.
Hope it helps, at least a bitt:)
