Saturn
( Shani ) and Ketu in 7th house of Gemini ( Mithuna ) rashi ( zodiac )
is not very encouraging. Saturn and ketu both are going to give negative
result from marriage point of view as 7th house denotes marriage.
Saturn will delay the marriage and would create hurdles in finalization
of marriage.
On the other hand Ketu who has the nature of loosing
interest on the house matter where it is positioned because of the past
life karma where it had experienced the 7th house affairs, so in this
life doesn't have interest in such matter. This effect of ketu will not
produce interest in the person to get married. He will love to leave an
unmarried life ( Vairagya ).
With other planets combination effect it is
also seen that Saturn and Ketu in 7th house give intercaste marriage (
not marrying in same community ) and sometime unnatural difference in
husband and wife. May be the wife of the person is much more older than
his husband. Marries a persons having different religion.
