Nasdaq and the Zodiac
Saul Behr in Johannesburg, SA wrote
Somebody recently came up to me, and gave me unsolicited information about astrology. From a reliable source, with a good history of accuracy, he gave me some tips on the stock market. Am I allowed to act on that information?
There's no problem with acting on this unsolicited advice. However, one should not actively seek out such advice. Rather, a Jew should go about life trusting that G-d will "be there" for him, and not feel the need to know the future.
Note that ultimately, astrology has no bearing on the life of a Jew because "ain mazel b'yisrael -- the people of Israel transcend astrological influences."
