The word translated as "perfect" (Tamim) can also mean "blameless", as well as "simple". The Torah puts limits on our desires to know, or alter, the future. If we disregard for the moment RAMBAM's view that all of these actions are intrinsically forbidden, are we about manipulating G-d and His plans? If something unpleasant has, in G-d's plans, been decreed against us (chas v'Shalom), should we then try to "trick" him into not following through? G-d will, however, heed our pleas (again, disregarding RAMBAM's view that G-d is unmoved by our prayers). Both the Tanach and Talmud are filled with passages about the efficacy of supplication. The Divine Oracle, the Urim v'Tummmim, which existed from the time of Moses until the destruction of the First Temple, was only allowed to be consulted by the King, and then only in a matter of national concern. Tarot cards, feature Jewish, Christian, and Pagan symbols. Their connection with idolatry is unmistakable. But even if we go beyond that, is asking cards for guidance being "perfect" or "simple" with G-d? Psychics? The scientific jury is still out. Many things simply cannot be explained. I have two personal friends who claim to be psychics. About five years ago, Sima was diagnosed with a serious illness, with little hope held out. Both of these friends told us that the diagnosis was not correct. We learned three years later that they were right, and that the doctor had been ashamed to tell us of his error. I cannot give a rational explanation for this. But when I thought that she was in grave danger, I turned to prayer,not to magic. As to astrology, although RAMBAM declared it forbidden even to beleive in it, most of the Rabbis of the Talmud did, and many later rabbis were professional astrologers. The consensus in the Talmud is that it is indeed real, but we are not to delve into it too much. However, if we should hear something from an astrologer, we should take his words seriously. I used to not beleive in astrology. But when we lived in Israel, there was an astrologer on the radio every Friday morning named Miriam Binyamini. Her predictions were so specific (you will receive an unexpected check on Tuesday), and so accurate, that I changed my opinion. Once, Sima said "you listen to her. My feet hurt, and I need to lie down". A few seconds later, the astrologer said "all you Libras (Sima's sign) are feeling pain in your feet, so go lie down".Can I explain it? No, I can't. But I know that there is much in the world that we don't understand, and probably never will.But if we remember that we live in G-d, that will grant us peace of mind, as well as perspective. One of the Names of G-d is "Shaddai. This name has several interpretations. One of these is "sheday" (He is enough). G-d is sufficient for all of our needs; we need not look elsewhere.
