Matsya Purana — Division of Bhārata-varṣa
इक्षुर्लौहितम् इत्येता हिमवत्पार्श्वनिःसृताः वेदस्मृतिर् वेत्रवती वृत्रघ्नी सिन्धुरेव च पर्णाशा नर्मदा चैव कावेरी महती तथा //
ikṣurlauhitam ityetā himavatpārśvaniḥsṛtāḥ vedasmṛtir vetravatī vṛtraghnī sindhureva ca parṇāśā narmadā caiva kāverī mahatī tathā //
‘Ikṣu’ and ‘Lauhita’—these rivers arise from the flanks of the Himalaya; so too are Veda-smṛti, Vetravatī, Vṛtraghnī, and the Sindhu; likewise Parṇāśā, the Narmadā, the Kāverī, and the great river Mahatī.
This verse is not about Pralaya; it catalogs sacred rivers and states that several are said to originate from the Himalayan region.
Indirectly, by identifying revered rivers central to tīrtha practice—kings and householders are encouraged in Purāṇic ethics to support pilgrimage, river-protection, and merit-making rites connected with such waters.
Ritually, the verse functions as a tīrtha-geography reference: these named rivers are traditional locations for bathing (snāna), offerings (tarpaṇa), and vows (vrata), often linked to temple-sites and pilgrimage circuits.
