Matsya Purana — Kṛṣṇāṣṭamī Vrata: Monthly Śiva-Names
देवाय दद्यादर्घ्यं च कृष्णां गां कृष्णवाससम् दद्यात्समाप्ते दध्यन्नं वितानध्वजचामरम् //
devāya dadyādarghyaṃ ca kṛṣṇāṃ gāṃ kṛṣṇavāsasam dadyātsamāpte dadhyannaṃ vitānadhvajacāmaram //
One should offer arghya to the deity, and also give a black cow together with a black garment. At the conclusion of the rite, one should donate rice mixed with curds, along with a ceremonial canopy (vitāna), a banner (dhvaja), and a yak-tail fan (chāmara).
This verse does not address pralaya; it focuses on ritual etiquette—offerings to the deity and prescribed gifts at the completion of a religious observance.
It frames dāna (charitable giving) as a dharmic duty: a householder (and by extension a king as patron) should honor the deity with arghya and support religious order through specified donations at a rite’s conclusion.
The items vitāna (canopy), dhvaja (banner), and cāmara (yak-tail fan) are honorific ritual accessories used in pūjā and festival processions, indicating a formal, temple-style completion of worship rather than domestic worship alone.
