Kateey Tarpan Puja is a sacred Hindu ritual performed to honor and appease the souls of ancestors. Conducted especially during Pitru Paksha or on specific Amavasya (new moon) days, this ritual involves offering water, sesame seeds, and sacred grass (kusha) while chanting mantras. “Kateey” refers to a specific ancestral lineage or group, and tarpan means offering. The purpose of the puja is to seek blessings, peace, and liberation (moksha) for the departed souls. It is believed that performing Kateey Tarpan with devotion brings prosperity, removes obstacles, and strengthens familial bonds through ancestral grace and spiritual harmony in the household.
