Matsya Purana — Glory of Tīrtha-Śrāddha: Best Times
वैदर्भा वाथ वैरा च पयोष्णी प्राङ्मुखा परा कावेरी चोत्तरा पुण्या तथा जालंधरो गिरिः //
vaidarbhā vātha vairā ca payoṣṇī prāṅmukhā parā kāverī cottarā puṇyā tathā jālaṃdharo giriḥ //
Also (are praised) the Vaidarbhā and Vairā (rivers/regions), and the Payoṣṇī; likewise the Prāṅmukhā, the eminent Parā; and the holy Kāverī flowing northward—together with the mountain Jālaṃdhara.
This verse does not discuss Pralaya; it is part of a sacred-geography catalogue, praising rivers and a mountain as holy supports of dharma and pilgrimage merit.
By identifying specific rivers/regions as puṇya (merit-giving), it implicitly guides kings and householders toward tirtha-yatra and ritual bathing/donations performed at renowned waters—standard Purāṇic duties linked to purification and public religiosity.
Ritually, the verse highlights named waters as sacred—useful for snāna (purificatory bathing), saṅkalpa rites, and selecting auspicious locales; such tirtha recognition often underlies later temple siting and consecration practices near holy rivers.
