Mangal Dosh Puja Ujjain According to Indian mythology, the pilgrimage city of Ujjain is considered to be the holy site of serpents and since this worship is related to the Nag Yoga of planets, Kalsarp Dosh can be best prevented in this city itself. Kaal Sarp Dosh Puja is also commonly known as Kaal Sarp Yog Puja. It is believed that this worship is done only when all the astrological planets come between Ketu and Rahu, you all must know the story of Rahu and Ketu, how Lord Vishnu divided them into two parts due to deceitful drinking of nectar. Mangal Dosh Puja Ujjain Rahu and Ketu should be made, from this point of view both of them are immortal, but due to lack of divinity in them, they have sinful planets and are bitter. This problem is solved by worshiping Kaal Sarp Dosh. ,
