Matsya Purana — Rasakalyāṇinī Vrata: Magha-based Goddess Worship
जलपूरितं तथा कुम्भं शुक्लाम्बरयुगद्वयम् दत्त्वा सुवर्णकमलं गन्धमाल्यैः समर्चयेत् //
jalapūritaṃ tathā kumbhaṃ śuklāmbarayugadvayam dattvā suvarṇakamalaṃ gandhamālyaiḥ samarcayet //
Having offered a water-filled pot (kumbha) along with a pair of white garments, one should then present a golden lotus and worship it well with fragrances and garlands.
This verse does not address pralaya directly; it focuses on meritorious ritual action—offering a water-filled kumbha, white cloth, and a golden lotus as part of worship.
It reflects the householder (and kingly) duty of dana and puja: making pure offerings (water vessel, clean white garments) and performing reverent worship with gandha and garlands to cultivate punya and uphold dharma.
Ritually, the kumbha is a standard sacred vessel used to establish auspiciousness and invoke sanctity; the white garments signal purity, and the golden lotus functions as a high-value devotional offering honored with fragrance and floral garlands.
