Just as each of us has muscles or bones, every human being has within himself the capacity of clairvoyance. The difference lies in what we do with that opportunity. There are psychics who have not needed to develop their gifts, but most of them really worked their potential to optimize it. To work this potential, it is essential to have an ethical life, a spiritual life, and have a lifestyle that encourages the emergence of the gifts of clairvoyance. You have to believe, but especially work your extra-sensory perceptions potential to be competent.
