In the vast tapestry of Sanatana Dharma, the performance of Shraddha (ancestral rites) is considered one of the most crucial nitya karmas (daily duties) for a householder. However, within the Sri Vaishnava Sampradaya—the tradition following the Vishishtadvaita philosophy of Ramanujacharya—these rites take on a uniquely devotional coloring. The term refers to the specific procedural manual ( Prayoga ) for conducting ancestral ceremonies in accordance with the Pancharatra Agama, Divya Prabandham, and the teachings of the Alvars and Acharyas.
