Can Narayan Bali be performed in Varanasi for ancestors who died unnaturally many years ago?

Yes, absolutely. If a family continues to face unexplained hardships or misfortunes attributed to Pitru Dosha stemming from an ancestor’s unnatural death, performing Narayan Bali in Varanasi (especially at Pishach Mochan) is highly recommended, regardless of how much time has passed since the death occurred. The potency of the location is believed to effectively address long-standing ancestral issues.
