By combining the power of symbols and the influence of fate, the use of cards can give the ability to do predictions for everybody. This only requires a strong faith in life and a good intuition. It is important to note that like any other senses, intuitiveness (the 6th Sense) is present within everyone but its effectiveness can vary. The use of cards also gives the chance for the medium to read himself, however, the difficuty level is much higher because the hopes and fears can influence the reading.
The use of cards is a very powerful tool and it is one of the most popular method for that reason. Not only does it help to predict the past, present and future with an impressive accuratecy, but it is also a very good tool for reveiling unconscious and repressed thoughts.
There are many different decks available in the market today and it is not only their appearence who is different, but also how they are used as well. The trick is to find the right deck for you. You have to be inspired when you look at them and it has to be natural when you read them. Even if you receive rules with the deck, dont esitate to modify them to your needs. Rules are importent but they have to be your own because if they are not, they become limitations stoping you from your true potential.
