Pitru Paksha: Why is Pind Daan at Punpun River done first. During Pitru Paksha, many devotees perform Pind Daan at Bihar's Punpun River before proceeding to Gaya for ancestral rituals. According to Hindu traditions, Punpun is considered significant for performing rites for departed ancestors. The ritual is believed to help honour and seek peace for the souls of deceased family members before the main Shraddha ceremony in Gaya.
