Matsya Purana — Rasakalyāṇinī Vrata: Magha-based Goddess Worship
*ईश्वर उवाच अथान्यामपि वक्ष्यामि तृतीयां पापनाशिनीम् रसकल्याणिनीमेतां पुराकल्पविदो विदुः //
*īśvara uvāca athānyāmapi vakṣyāmi tṛtīyāṃ pāpanāśinīm rasakalyāṇinīmetāṃ purākalpavido viduḥ //
Īśvara said: “Now I shall also describe another procedure—the third, the sin-destroying one. This is called the Rasakalyāṇinī, and the knowers of the ancient ritual ordinances (kalpa) have recognized it as such.”
This verse does not describe pralaya directly; it functions as a transition where the Lord introduces a third purificatory observance recognized by ancient ritual authorities.
It frames a prescribed pāpanāśinī (sin-removing) rite—relevant to kings and householders as part of ethical self-purification and maintaining ritual fitness before governance, charity, vows, or major religious acts.
The verse signals an authoritative ritual procedure (kalpa-based) called Rasakalyāṇinī, likely used as a purification or auspicious preparatory rite that can accompany Vastu/temple-related undertakings and consecratory contexts.
