Matsya Purana — Rasakalyāṇinī Vrata: Magha-based Goddess Worship
अनेन विधिना यस्तु रसकल्याणिनीव्रतम् कुर्यात्स सर्वपापेभ्यस् तत्क्षणादेव मुच्यते //
anena vidhinā yastu rasakalyāṇinīvratam kuryātsa sarvapāpebhyas tatkṣaṇādeva mucyate //
Whoever performs the Rasakalyāṇinī vow according to this prescribed method is released from all sins immediately, at that very moment.
This verse is not about Pralaya; it is a phalaśruti (promise of merit) stating that correct performance of a specific vrata grants immediate release from sins.
It supports the Purāṇic ethic that householders (and rulers as exemplars) should follow prescribed vratas and rituals as a means of self-purification and moral discipline, leading to pāpa-kṣaya (removal of demerit).
The significance is ritual rather than architectural: it emphasizes strict adherence to the stated विधि (procedure) for the Rasakalyāṇinī vrata, with the key takeaway that methodical observance is what yields the promised spiritual result.
