Matsya Purana — Lineage of the Pitṛs
अभयेत्युष्णतीर्थेषु चामृता विन्ध्यकन्दरे माण्डव्ये माण्डवी नाम स्वाहा माहेश्वरे पुरे //
abhayetyuṣṇatīrtheṣu cāmṛtā vindhyakandare māṇḍavye māṇḍavī nāma svāhā māheśvare pure //
Among the hot-water sacred fords is (the tirtha) called Abhayā; in the caves of the Vindhya is (the tirtha) called Amṛtā; at Māṇḍavya is one named Māṇḍavī; and in the city of Maheśvara is (the tirtha) called Svāhā.
This verse does not address Pralaya; it catalogs specific tirtha-names and locations, emphasizing sacred geography and the merit of pilgrimage rather than cosmic dissolution.
It supports the householder’s dharma of tīrtha-yātrā (pilgrimage) and ritual bathing as purificatory acts; for kings, such tirtha networks also function as sacred-cultural maps that legitimize patronage and protection of holy sites.
Ritually, it points to bathing/visiting named tirthas (including hot springs and cave-tirthas). Architecturally, the implication is indirect: such named sites commonly attract shrines and ghāṭas, forming pilgrimage infrastructure rather than prescribing Vastu rules in this specific verse.
