Matsya Purana — Sādhāraṇa Śrāddha: General Ancestral Rite
पितृपात्रे निधायाथ न्युब्जमुत्तरतो न्यसेत् पितृभ्यः स्थानमसीति निधाय परिषेचयेत् //
pitṛpātre nidhāyātha nyubjamuttarato nyaset pitṛbhyaḥ sthānamasīti nidhāya pariṣecayet //
Having placed it in the vessel meant for the ancestors, one should then set the vessel down with its mouth turned downward to the north. Placing it with the utterance, “You are the seat for the Pitṛs,” one should sprinkle water all around it.
This verse is not about pralaya; it belongs to ritual-dharma, prescribing the correct placement and consecration of the ancestral vessel during śrāddha.
It frames śrāddha as a required duty: a householder (and a righteous king as patron of dharma) should honor the Pitṛs by properly arranging the pitṛ-pātra, invoking it as their “seat,” and performing the purificatory sprinkling.
Ritually, it specifies northward placement and parisecana (circum-sprinkling) to establish a sanctified “seat” for the Pitṛs—key procedural details in Matsya Purana’s śrāddha guidelines.
