Matsya Purana — Division of Bhārata-varṣa
गोमती धौतपापा च बाहुदा च दृषद्वती कौशिकी तु तृतीया च निश्चला गण्डकी तथा //
gomatī dhautapāpā ca bāhudā ca dṛṣadvatī kauśikī tu tṛtīyā ca niścalā gaṇḍakī tathā //
Gomatī, Dhautapāpā, Bāhudā, and Dṛṣadvatī; and as the third, Kauśikī; likewise Niścalā and also Gaṇḍakī—these are counted among the sacred rivers.
This verse does not describe pralaya; it functions as a tirtha-geography catalogue, emphasizing rivers as purifying sacred realities within the living cosmos.
By naming rivers renowned for purification, the text supports the householder and ruler’s dharma of tirtha-yatra, ritual bathing, and merit-making acts that reinforce social-religious order.
Ritually, these rivers are invoked as places for snāna (sacred bathing) and related rites; the verse itself does not give Vastu rules but underpins temple/ghat ritual culture tied to river tirthas.
