These cards are undoubtedly very helpful for those who intend to be future clairvoyant or wanting to evoke their hidden spiritual talent. By concentrating on the ink blots and shapes they make is a very good practice for recognizing the symbols and shapes one observes during a trance state or meditation. Once you recognize the shapes and symbols on the cards, you can then tally them with the index of symbols provided for a particular meaning of that shape or symbol. But at the same time one must not forget that these sort of cards although are very helpful but with some psychic knowledge or basic concepts one can prepare these sort of cards on his or her own. But for those who dont know how to, these are the ones readily available and useful too.
