The Greatness of the Gaṅgā
Gaṅgāmāhātmya
सेयं गङ्गा महापुण्या नदी भक्त्या निषेविता । मेषतौलिमृगार्केषु पावयत्यखिलं जगत् ॥ २९ ॥
seyaṃ gaṅgā mahāpuṇyā nadī bhaktyā niṣevitā | meṣataulimṛgārkeṣu pāvayatyakhilaṃ jagat || 29 ||
此即恒河（Gaṅgā）——功德无量之圣河，为信众以奉爱（bhakti）恭敬亲近；当太阳行至梅沙（Meṣa，白羊）、陶利（Taulī，天秤）与“鹿”（Mṛga，Mṛgaśīrṣa时节/日行段）之时，她净化整个世界。

FAQs
It declares Gaṅgā as a universally purifying tīrtha whose sanctity is activated through bhakti (devotional resorting), emphasizing her role as a dharma-supporting purifier for all beings.
Purification is not presented as merely physical contact with water but as ‘bhaktyā niṣevitā’—approaching and serving Gaṅgā with reverence—showing that inner devotion is central to the fruit of tīrtha-sevā.
It points to Jyotiṣa (Vedic astrology) by naming specific solar placements (Meṣa, Taulī, Mṛga) as spiritually potent times for tīrtha practices like Gaṅgā-snāna.
