Matsya Purana — Rasakalyāṇinī Vrata: Magha-based Goddess Worship
प्रीयतामत्र कुमुदा गृह्णीयाल्लवणव्रतम् अनेन विधिना देवी मासि मासि सदार्चयेत् //
prīyatāmatra kumudā gṛhṇīyāllavaṇavratam anena vidhinā devī māsi māsi sadārcayet //
“May Kumudā be pleased here. One should undertake the Salt-Vow (Lavaṇa-vrata); by this very procedure the Goddess should be worshipped continually, month after month.”
Nothing directly—this verse is focused on vrata-dharma (a devotional vow) and repeated monthly worship of the Goddess, not on pralaya cosmology.
It presents a practical dharmic duty: undertaking a regulated vow (lavaṇa-vrata) and maintaining consistent month-by-month worship—an ideal of disciplined observance applicable to householders and rulers alike.
Ritual significance: it prescribes a specific vow and emphasizes periodic (monthly) continuity of Devi-arcana “by this method,” pointing to standardized procedure rather than temple-architecture details.
