FAQs
Ancestral duty (pitṛ-ṛṇa) is fulfilled through śrāddha, and tīrthas amplify its merit.
River tīrthas in general—especially rivers that culminate in the ocean—are praised as powerful venues for śrāddha.
Perform śrāddha (at minimum at home), with a stronger recommendation to do it at a sacred river for multiplied fruit.
