Matsya Purana — Rasakalyāṇinī Vrata: Magha-based Goddess Worship
तद्वद्गोमिथुनं शुक्लं सुवर्णास्यं सिताम्बरम् सवस्त्रभाजनं दद्याद् भवानी प्रीयतामिति //
tadvadgomithunaṃ śuklaṃ suvarṇāsyaṃ sitāmbaram savastrabhājanaṃ dadyād bhavānī prīyatāmiti //
In the same manner, one should give a pair of white cattle, with golden-faced adornment, clothed in white garments, together with vessels and clothing, uttering: “May Bhavānī be pleased.”
This verse does not address pralaya; it belongs to the dāna (ritual charity) instructions focused on merit-making and pleasing the Goddess Bhavānī.
It prescribes a meritorious form of go-dāna (gift of cattle) with proper accompaniments (clothing and vessels) and a clear dedication formula—an exemplary householder/kingly duty of charity done with intention (saṅkalpa) and devotion.
The ritual significance is the specified dāna package (white cattle, white garments, vessels) and the spoken dedication “Bhavānī prīyatām,” showing how offerings are consecrated through mantra-like intent rather than architecture or vāstu.
