Matsya Purana — Lineage of the Pitṛs
गोमन्ते गोमती नाम मन्दरे कामचारिणी मदोत्कटा चैत्ररथे जयन्ती हस्तिनापुरे //
gomante gomatī nāma mandare kāmacāriṇī madotkaṭā caitrarathe jayantī hastināpure //
At Gomanta (mountain) is the holy river named Gomatī; at Mandara is Kāmacāriṇī; at Caitraratha is Madotkaṭā; and at Hastināpura is Jayantī.
This verse does not describe Pralaya; it catalogs sacred rivers/holy sites connected with specific mountains and regions, emphasizing pilgrimage geography rather than cosmic dissolution.
By mapping recognized tīrthas, it supports the householder and kingly duty of dharma through tīrtha-yātrā, charity, and ritual bathing—acts traditionally recommended for purification and public religious merit.
The ritual takeaway is tīrtha-identification: these named rivers/sites are implied places for snāna (sacred bathing) and pilgrimage observances; no direct Vastu or temple-construction rule is stated in this verse.
