Which puja is best for Pitru Dosh nivaran?

The best puja for Pitru Dosh nivaran depends on the underlying cause. If the Pitru Dosh is caused by an ancestor who died an unnatural or premature death (accident, suicide, drowning, murder), Narayan Bali Puja is the prescribed remedy per the Garuda Purana. It performs a symbolic last rites for the trapped soul, releasing it from preta yoni. If the cause is generational neglect of Shradh and Tarpan, Pind Daan at Gaya or Prayagraj addresses the accumulated ancestral debt. For families where Shradh has not been performed for three or more consecutive years, Tripindi Shradh is specifically prescribed. Many families require a combination — Narayan Bali for the unnatural death plus Pind Daan for the neglected lineage — and performing both in a single visit to Prayagraj or Gaya is both permitted and recommended.
