Matsya Purana — Kailasa
दृश्यते भासुरा रात्रौ देवी त्रिपथगा तु सा अन्तरिक्षं दिवं चैव भावयित्वा भुवं गता //
dṛśyate bhāsurā rātrau devī tripathagā tu sā antarikṣaṃ divaṃ caiva bhāvayitvā bhuvaṃ gatā //
At night she is seen shining with brilliant radiance—the goddess Tripathagā (Gaṅgā); having pervaded the mid-region and heaven with her presence, she then proceeds to the earthly realm.
It does not describe pralaya directly; it presents a cosmological vision of Gaṅgā spanning heaven, the mid-region, and earth—implying a stable three-tier cosmos rather than dissolution.
By praising Gaṅgā as Tripathagā, the verse supports tīrtha-oriented dharma: rulers and householders gain merit through honoring sacred rivers, undertaking pilgrimages, and supporting rites connected with holy waters.
Ritually, it underscores Gaṅgā’s sanctity across realms—supporting practices like snāna (sacred bathing), ācamana, and water-offerings; architecturally, it indirectly legitimizes ghāṭa and tīrtha constructions aligned to river worship.
