Matsya Purana — The Observance of Ananta-Tritiya
गोमूत्रं गोमयं क्षीरं दधि सर्पिः कुशोदकम् बिल्वपत्त्रार्कपुष्पं च यवान्गोशृङ्गवारि च //
gomūtraṃ gomayaṃ kṣīraṃ dadhi sarpiḥ kuśodakam bilvapattrārkapuṣpaṃ ca yavāngośṛṅgavāri ca //
Cow’s urine, cow-dung, milk, curd (dadhi), and ghee; water sanctified with kuśa grass; bilva leaves and arka flowers; barley; and water poured (or kept) in a cow-horn—these are the purificatory substances to be used in the rite.
This verse is not about pralaya; it belongs to ritual-ācāra material and lists purifying substances used in ceremonies and expiations.
It supports the householder’s and ruler’s duty to maintain ritual purity in domestic rites, public ceremonies, and prāyaścitta—using pañcagavya-related items, kuśa-water, and other sanctioned materials.
Ritually, it specifies standard purification media (pañcagavya set plus kuśodaka, bilva/arka, yava, and gośṛṅga-vāri) commonly used for sprinkling, cleansing, and sanctifying before worship, consecrations, or expiatory acts.
