Matsya Purana — Rasakalyāṇinī Vrata: Magha-based Goddess Worship
आनन्दायै सुनन्दायै सुभद्रायै नमो नमः एवं सम्पूज्य विधिवद् द्विजदाम्पत्यम् अर्चयेत् भोजयित्वान्नपानेन मधुरेण विमत्सरः //
ānandāyai sunandāyai subhadrāyai namo namaḥ evaṃ sampūjya vidhivad dvijadāmpatyam arcayet bhojayitvānnapānena madhureṇa vimatsaraḥ //
Obeisance again and again to Ānandā, Sunandā, and Subhadrā. Having thus duly worshipped according to rule, one should reverentially honour the twice-born couple; and, free from envy, feed them with sweet food and drink.
This verse does not discuss Pralaya; it focuses on ritual propriety—offering salutations and honouring a twice-born couple through worship and feeding.
It teaches dharmic conduct: properly performing worship, respecting learned Brahmins (especially a household pair), and practising atithi-sevā and anna-dāna without jealousy—core duties for householders and also exemplary royal patronage.
The significance is ritual: a prescribed pūjā-vidhi culminating in honouring and feeding the dvija-dāmpatya with sweet food and drink, emphasizing correct procedure (vidhivat) and pure intention (vimatsara).
