Matsya Purana — Kamalā-Saptamī Vow: Lotus Rite for Sūrya
व्रतान्ते शयनं दद्यात् सुवर्णकमलान्वितम् गां च दद्यात्स्वशक्त्या तु सुवर्णाढ्यां पयस्विनीम् //
vratānte śayanaṃ dadyāt suvarṇakamalānvitam gāṃ ca dadyātsvaśaktyā tu suvarṇāḍhyāṃ payasvinīm //
At the conclusion of the vow (vrata), one should donate a bed furnished with a golden lotus. And, according to one’s means, one should also give a milch cow adorned with gold.
This verse does not address pralaya; it focuses on dharmic practice—how to conclude a religious vow through prescribed gifts (dāna) to accrue merit (puṇya).
It sets a householder-style dharma norm: after completing a vrata, one should formalize the conclusion with charity—donating a bed and, as one’s resources allow, a milch cow adorned with gold—emphasizing generosity proportionate to capacity (svaśaktyā).
Ritually, it describes vrata-samāpti dāna: gifting a “śayana” (bed) embellished with a golden lotus and a “payasvinī” cow. The items are symbolic, high-merit gifts used in Purāṇic ritual economy rather than temple architecture rules.
