Cards: Tarot or otherwise, it matters not. Although Tarot books usually give the traditional meanings of each card, there is nothing to stop anyone from reading cards psychically or even mediumistically.
Angel cards or playing cards can be used too. There is such a variety of cards in the stores now, with great use of colour and good illustrations, both in ancient and in modern styles.
There are usually one or two novices at my workshops who learn to read psychically by using cards as a focal point. It just seems to work for them.
The need to give the meaning for each card separately is negated by using psychic talents. I am in no way decrying Tarot readers, as I know there are some genuinely good ones out there, amongst the many who profess to be.
