In Indian astrology seventh is most important house in the worldly sense. In a horoscope it is the house of all partnerships including spouse. So all matters pertaining to marriage are ascertained from the seventh house. The planets which occupy the 7th house, their star lords and planet owning the 7th house are very important to know the happiness of married life. 7th lord should not be in 6th 8th or 12th from the 7th for a happy marriage as per Vedic astrology.
Similarly Saturn or Raahu in 7th can give marriage with an elderly person or a widow/widower or divorcee. Mars there is a sure guarantee of two marriages. Jupiter in this house of the horoscope makes the spouse obese, mercury is a danger sign as the partner may be incapable of sex.
