गङ्गाजन्मवर्णनम् / The Origin of the Ganga (Tripathagā Narrative)
या मेरुदुहिता राम तयोर्माता सुमध्यमा।नाम्ना मनोरमा नाम पत्नी हिमवत: प्रिया।।1.35.15।।
tasyāṃ gaṅgeyam abhavaj jyeṣṭhā himavataḥ sutā | umā nāma dvitīyābhūn nāmnā tasyaiva rāghava ||
“From her was born this Gaṅgā, the eldest daughter of Himavān. The second daughter, O Rāghava, was born to him and was known by the name Umā.”
O Rama! Himavan's beloved of beautiful waist, well-known by the name of Manorama is the daughter of Mount Meru. She is the mother to both the daughters.
Dharma here is the ordered understanding of the sacred world: rivers and deities are not random forces but belong to a moral-cosmic structure conveyed through truthful tradition.
Viśvāmitra names Himavān’s two daughters—Gaṅgā as the elder and Umā as the younger—advancing the origin-story Rāma requested.
Viśvāmitra’s fidelity to sacred history (satya in transmission) is emphasized by careful identification of figures.
