Rahu and Ketu are north and south nodes

     Kaal Sarpa Yoga(KSY) is a bad yoga which rises when all the seven planets namely Sun, Moon, Mars, Mercury, Jupiter, Venus and Saturn are located on one side of Rahu and Ketu.

     Astrologers say Rahu is head of serpent while Ketu is tail of a serpant and location of seven planets on one side allows Rahu and Ketu to negate the effects of all those powerful seven planets. Normally its observed Kaal Sarpa Yoga from ascendant seems to trouble natives a lot. Rahu or Ketu placed in ascendant and all seven planets placed from first house to seventh house or seventh house to first house seems to cause maximum troubles.

     Praying to Lord Shiva helps when you have Kaal Sarpa Yoga. Reciting the Mrityunjay and Maha-Mrityunjay Japa also greatly reduces the ill-effects of this yoga. Other than that there is Kaal Sarp Yoga puja which is done near a river bank which also seems to pacify KSY.

     There are many people who panic like end of the world crisis if they have KSY. Many successful people have this yoga including the likes of Abraham Lincoln, Jawaharlal Nehru, Sachin Tendulkar and Dhirubhai Ambani. A horoscope doesn't make or break an individual. A person's hard work and character makes a success or failure out of him/her.

     Don't over-panic and don't think of KSY as a weight that's pulling you down. Its just one of the countless bad yogas that can happen in a horoscope.
