गङ्गाजन्मवर्णनम् / The Origin of the Ganga (Tripathagā Narrative)
एतत्ते सर्वमाख्यातं यथा त्रिपथगा नदी।खं गता प्रथमं तात गतिं गतिमतां वर ।।1.35.23।।
ugreṇa tapasā yuktāṃ dadau śailavaras sutām |
rudrāyāpratirūpāya umāṃ lokanamaskṛtām || 1.35.21 ||
Himavān, best of mountains, gave his daughter Umā—endowed with severe austerity and revered by the world—to Rudra, the peerless one.
O child with a marvellous gait! I have related to you about Ganga flowing across the three worlds, Ganga who reached the heaven first and all that.
Dharma as rightful alliance: marriage is portrayed as a dharmic giving, grounded in merit (tapas) and cosmic suitability.
Viśvāmitra states that Umā, famed for austerity, was given by Himavān in marriage to Rudra.
Umā’s ascetic excellence and Himavān’s adherence to social-religious propriety in arranging a fitting union.
