Saturn transiting through 12th house to the 2nd house arises Shani Sade Sati. This time period is of 7.5 years which is considered as malefic and inauspicious for the native.
The native has to face a lot of challenges and hurdles during this period. Saturn gives malefic rewards if ill-placed but it is said that sade sati is not always unfortunate. Many a times, Saturn give good results to the natives who worked hard and remained disciplined in the past.
What an individual do during this period sets his rewards for next 23 years when Saturn starts falling into 12 house again.
