Kaal Sarp Dosh is also known as Kaal Sarp Yog. It is one of the most disturbing astrological consolidations that can bring bad luck in one’s life. Kaal Sarp Yog is built in one’s Kundli. It takes place when all the seven important planets are placed betwixt Rahu and Ketu. However, Rahu serve as the snake’s head and Ketu denotes the snake’s tail. Also, the presence of this Yoga in one’s Kundali can have some bad effects on the person.
