Matsya Purana — Division of Bhārata-varṣa
त्रिभागा ऋषिकुल्या च इक्षुदा त्रिदिवाचला ताम्रपर्णी तथा मूली शरवा विमला तथा महेन्द्रतनयाः सर्वाः प्रख्याताः शुभगामिनीः //
tribhāgā ṛṣikulyā ca ikṣudā tridivācalā tāmraparṇī tathā mūlī śaravā vimalā tathā mahendratanayāḥ sarvāḥ prakhyātāḥ śubhagāminīḥ //
Tribhāgā, R̥ṣikulyā, Ikṣudā, Tridivācalā, Tāmraparṇī, Mūlī, Śaravā, and Vimalā—these are all renowned rivers said to be the daughters of Mahendra, auspicious in their course and beneficent to those who approach them.
This verse is not describing Pralaya; it catalogs sacred rivers, emphasizing auspicious natural features of the world that remain central to pilgrimage and ritual life.
By identifying renowned, auspicious rivers, the text supports dharmic duties such as tīrtha-yātrā, ritual bathing, ancestral rites, and charitable acts performed at sacred waters—practices encouraged for householders and patronized by kings.
Ritually, these rivers function as tīrthas where स्नान (sacred bathing), offerings, and rites gain merit; architecturally, sacred rivers guide temple-town siting and auspicious landscape selection (a common Vastu-aligned principle even when not explicitly stated in this verse).
