Matsya Purana — Rasakalyāṇinī Vrata: Magha-based Goddess Worship
क्षीरं शाकं च दध्यन्नम् इण्डर्यो ऽशोकवर्तिकाः माघादिक्रमशो दद्याद् एतानि करकोपरि //
kṣīraṃ śākaṃ ca dadhyannam iṇḍaryo 'śokavartikāḥ māghādikramaśo dadyād etāni karakopari //
Beginning with the month of Māgha and proceeding in due order, one should offer milk, vegetables, rice mixed with curds (dadhyanna), iṇḍarya, and wicks (vartikā) made from the aśoka tree—placing these items upon a water-pot (karaka).
This verse does not address pralaya; it focuses on a dharma-oriented ritual schedule—specific offerings to be made month-by-month beginning in Māgha.
It prescribes orderly dāna/vrata conduct: a householder (and likewise a king as exemplar) should perform regulated monthly offerings using specified pure items, emphasizing discipline, charity, and ritual correctness.
The ritual significance is the use of a karaka (water-pot) as the placement/base for offerings, and the inclusion of aśoka-vartikā (aśoka wicks), indicating a lamp/rite component within a structured monthly observance.
