Matsya Purana — The Viśokā-Saptamī Vow
व्रतान्ते कलशं दद्यात् सुवर्णकमलान्वितम् शय्यां सोपस्करां दद्यात् कपिलां च पयस्विनीम् //
vratānte kalaśaṃ dadyāt suvarṇakamalānvitam śayyāṃ sopaskarāṃ dadyāt kapilāṃ ca payasvinīm //
At the completion of the vow, one should gift a ritual water-pot (kalaśa) adorned with a golden lotus. One should also donate a bed complete with its furnishings, and a tawny milch-cow (kapilā) rich in milk.
This verse is not about Pralaya; it focuses on dharma—specifically the proper completion of a religious vow (vrata) through prescribed charitable gifts (dāna).
It presents a householder-style dharma guideline: after completing a vow, one should formalize the merit through dāna—offering a kalasha, a furnished bed, and a milch-cow—acts that support ritual order, hospitality, and sustenance in society.
The ritual significance is the vrata-conclusion (udvāsana/vratānta) dāna: a kalasha (sacred vessel) adorned with a golden lotus is a formal ritual gift, while the bed with furnishings and the milch-cow represent complete, practical charity supporting comfort and nourishment.
