This is common believe that cross on Jupiter give Love marriage or early marriage. People do say the married life is normally of good quality. But I call this a Myth . Since I have come across many people with cross on Jupiter but they did not have Love marriage or good quality married life .
Few Days back a client came to me she had cross on Mount of Jupitar but at the same time also her marriage line was going down and touching heart line which is not auspicious sign . This could give her separation even death of a spouse . So I always tell my Student just do not conclude with one sign on hand see many more to certify event .
