Matsya Purana — The Sarasvata Vrata: Vow for Sweet Speech
समाप्ते तु व्रते कुर्याद् भोजनं शुक्लतण्डुलैः पूर्वं सवस्त्रयुग्मं च दद्याद्विप्राय भोजनम् //
samāpte tu vrate kuryād bhojanaṃ śuklataṇḍulaiḥ pūrvaṃ savastrayugmaṃ ca dadyādviprāya bhojanam //
When the vow is completed, one should prepare a meal with white rice; and first, together with a pair of garments, one should offer a Brahmin a meal.
This verse does not address Pralaya; it focuses on dharma—specifically the proper concluding rite (udyāpana) of a vow through feeding and gifting.
It sets a householder-style dharma norm: after completing a vrata, one should perform charitable acts—feeding a Brahmin and giving clothing—signaling gratitude, ritual completion, and social-religious responsibility.
The ritual takeaway is udyāpana protocol: prepare an auspicious meal (white rice) and prioritize dana—food and a pair of garments—to a qualified Brahmin as the formal closure of the vow.
