Matsya Purana — Śarkarā-Saptamī Vrata: The Sugar Offering Rite to Savitṛ
सुवर्णाश्वः प्रदातव्यः पूर्ववन्मन्त्रवादनम् न वित्तशाठ्यं कुर्वीत कुर्वन्दोषं समश्नुते //
suvarṇāśvaḥ pradātavyaḥ pūrvavanmantravādanam na vittaśāṭhyaṃ kurvīta kurvandoṣaṃ samaśnute //
A horse (or horse-figure) of gold should be given, accompanied—just as before—by the recitation of mantras. One should not practice deceit regarding wealth; for the one who does so incurs (and must bear) the fault.
This verse does not address pralaya; it focuses on dāna-dharma—how gifts should be given with mantra-recitation and with honesty.
It frames charity as a disciplined duty: a king or householder should give prescribed gifts (here, a golden horse) following ritual procedure, and must avoid financial deceit, since cheating in giving produces moral demerit.
The ritual point is “pūrvavat mantravādanam”—the donation must be accompanied by proper mantra-recitation as laid down earlier, emphasizing correctness of rite and purity of intent rather than any architectural rule.
