What is the specific importance of Narayani Shila Temple in Haridwar for Shradh?

Narayani Shila Temple is dedicated to Lord Vishnu (Narayana), the preserver, whose blessings are sought for the salvation of ancestors. The ‘Shila’ (stone) is believed to embody Lord Vishnu himself. Performing Shradh, Pind Daan, or Narayan Bali puja here is considered exceptionally potent for ancestors who died unnatural deaths, are suffering in the spirit realm (Preta Yoni), or when seeking relief from severe Pitru Dosh (ancestral afflictions). Offerings made here are believed to directly appease Lord Vishnu for the ancestors’ liberation.
