Matsya Purana — Genealogy and Classification of Sacred Fires
कावेरीं कृष्णवेणीं च नर्मदां यमुनां तथा गोदावरीं वितस्तां च चन्द्रभागामिरावतीम् //
kāverīṃ kṛṣṇaveṇīṃ ca narmadāṃ yamunāṃ tathā godāvarīṃ vitastāṃ ca candrabhāgāmirāvatīm //
Kāverī, Kṛṣṇaveṇī, Narmadā, and likewise Yamunā; Godāvarī and Vitastā as well; and also Candrabhāgā and Irāvatī—these sacred rivers are to be remembered and revered.
This verse does not describe pralaya; it functions as a tīrtha-style enumeration, emphasizing sacred geography—rivers revered for purity and merit.
By naming major sacred rivers, the verse supports dharmic practice such as tīrtha-yātrā, bathing, offerings, and remembrance—acts recommended for householders and supported by kings through protection of pilgrimage routes and riverbanks.
Ritually, these rivers are invoked for purification (snāna), offerings (tarpana), and merit; architecturally, river proximity commonly frames tīrtha layouts (ghāṭas, temples, and ritual precincts), though no specific Vāstu rule is stated in this line.
