Matsya Purana — Navagraha Sacrifice for Planetary Pacification and Prosperity
श्रावयेत्सूक्तमाग्नेयं वैष्णवं रौद्रमैन्दवम् महावैश्वानरं साम ज्येष्ठसाम च वाचयेत् //
śrāvayetsūktamāgneyaṃ vaiṣṇavaṃ raudramaindavam mahāvaiśvānaraṃ sāma jyeṣṭhasāma ca vācayet //
He should have the Agni-sūkta heard, as well as the Vaiṣṇava, Raudra, and Aindava (Soma-related) hymns; and he should also have the Mahāvaiśvānara Sāman and the Jyeṣṭha-sāman chanted.
This verse is not about Pralaya; it prescribes specific Vedic hymns and Sāman chants to be heard/recited in a ritual context, emphasizing orderly liturgical practice rather than cosmology.
It frames dharmic duty as supporting correct Vedic performance—ensuring qualified recitation and attentive hearing of hymns to Agni, Viṣṇu, Rudra, and Soma—typical responsibilities of householders and patrons (including kings) who sponsor rites and uphold religious order.
The significance is ritual: it lists authoritative hymns and Sāmaveda melodies (Mahāvaiśvānara and Jyeṣṭha-sāman) to be chanted, indicating which sacred sound-forms are considered appropriate for the ceremony being described.
