No, there is no set time limit. I’ve had spirit people come through many years after they’ve passed away — sometimes 30, 40, or even 50 years — or it could be as soon as one day. A friend of mine, Michael, passed away sadly due to complications from AIDS some years ago, and I remember being in his and his partner’s home for the memorial service. His partner had spent some time setting up a room upstairs beautifully, with a handsome picture of Michael with some of the amazing artworks that he had drawn during his lifetime. While I was saying my goodbyes, I heard his voice speak softly in my ear: “John, please tell Amanda that I will do what I can from here to help her with money.”
Michael Shermer criticized mediums in Scientific American, saying, "mediums are unethical and dangerous: they prey on the emotions of the grieving. As grief counselors know, death is best faced head-on as a part of life." Shermer wrote that the human urge to seek connections between events that may form patterns meaningful for survival is a function of natural evolution, and called the alleged ability of mediums to talk to the dead "a well-known illusion of a meaningful pattern."
Celtic Cross Tarot card reading predicts your future by reading the cards. This is different from prophesies using calculations of date, time and year of birth. Each prediction or card selection may not indicate the same result. The accuracy depends on your intention and concentration at the time of selection. Thus, it is very important to concentrate hard to achieve the most significant outcome.
