Flatland
A Romance of Many Dimensionsand describes an imaginary 2-dimensional world. In this fictional world everyone has width and length but no concept of height. The people, houses and whole society live in two dimensions and view the world as flat lines only. For example, the houses (like the image opposite) would seem totally enclosed and appear as flat lines with no way in or out except through the door.

slice, a dot would suddenly appear, progressively get larger until the end of the arrow head is reached then suddenly get smaller. It would stay the same for the length of the arrow and then totally vanish as the end is reached.

1. Your manager is planning to sack you or give you a promotion
2. Your partner is cheating on you
3. You have health issues (whether you know it or not)

5. If some rich uncle is planning to leave you money is his will
6. Who is really your friend and who is being deceitful
However as with all things there would be limitations, they would be unable to tell if:
1. You are going to win the lottery next week
2. You are going to meet the man/woman of your dreams

If spirits of the dead do dwell in 4 dimensions then our mere 3-dimensional world would be just a single plane (one of an infinite number) and they would be party to all that is going on. If they spoke the sound would come from within, items could appear and disappear or move around on their own. Most important of all, they could exercise control over the actions of our bodies such as the laying out of cards.
Of course this whole topic raises far more questions than it attempts to answer and blurs the lines into wider areas of theology, but it does offer an interesting concept. Some will take this a stage further and simply ask- If spirits have the ability to influence our world, why not write down or say a message? why do we need mediums of interpretation such as the Tarot?
. Well perhaps this influence is not quite so simplistic or direct but who knows?
