Matsya Purana — Vrata-Ṣaṣṭhī: The Sixty Sacred Vows
पायसाशी समान्ते तु दद्याद्विप्राय गोयुगम् लक्ष्मीलोकमवाप्नोति ह्य् एतद् देवीव्रतं स्मृतम् //
pāyasāśī samānte tu dadyādviprāya goyugam lakṣmīlokamavāpnoti hy etad devīvrataṃ smṛtam //
Living on pāyasa (rice cooked in milk) during the observance, one should, at its conclusion, gift a pair of cows to a Brāhmaṇa; thereby one attains the world of Lakṣmī—this is remembered as the Devī-vrata.
It does not discuss pralaya; it prescribes a Devī/Lakṣmī-oriented vrata, emphasizing dietary restraint and concluding charity as a means to attain Lakṣmī’s realm.
It models gṛhastha-dharma through vrata discipline (regulated food) and dāna (gifting cows to a brāhmaṇa), presenting prosperity (Lakṣmī-loka) as the fruit of ethical giving at the rite’s completion.
The ritual takeaway is the vrata’s proper closure: after subsisting on pāyasa, the practitioner should conclude by gifting a pair of cows—an orthodox dāna that completes (samāpti) the Devī-vrata.
