Matsya Purana — Eclipse-Time Planetary Bath
*मत्स्य उवाच यस्य राशिं समासाद्य भवेद्ग्रहणसम्प्लवः तस्य स्नानं प्रवक्ष्यामि मन्त्रौषधविधानतः //
*matsya uvāca yasya rāśiṃ samāsādya bhavedgrahaṇasamplavaḥ tasya snānaṃ pravakṣyāmi mantrauṣadhavidhānataḥ //
Lord Matsya said: “When, upon reaching a person’s rāśi (zodiacal sign), an eclipse-like calamity—namely a planetary affliction—arises, I shall prescribe for him the proper bathing rite, according to the ordained method of mantras and medicinal herbs.”
This verse is not about cosmic Pralaya; it uses “samplava” in the sense of an overwhelming calamity connected to grahaṇa (eclipse/affliction) and introduces a practical rite of purification.
It frames a householder-facing dharmic response to inauspicious celestial events: when afflicted, one should follow prescribed śānti practices—here, a purificatory bath supported by mantra and herbal means—rather than falling into fear or neglecting ritual discipline.
The significance is ritual (not architectural): it announces a specific snāna-vidhi (bathing procedure) to be performed during grahaṇa-related distress, explicitly integrating mantra-recitation with auṣadha (herbal/medicinal) ritual protocol.
