Can we do Kaal Sarp Dosh Puja at Ujjain?

Yes, absolutely. Ujjain is one of the most powerful locations in India for Kaal Sarp Dosh Puja, primarily because of Mangalnath Temple — the mythological birthplace of Mars (Mangal Graha) as described in the Matsya Purana. The puja is performed at Mangalnath Temple on the banks of the Shipra River, typically taking three to five hours. The combination of Mars energy at Mangalnath, Shiva blessing from Mahakaleshwar, and the Amrit-charged Shipra River makes Ujjain uniquely effective for serpentine dosha remedies.
