In this verse, Śukadeva Gosvāmī describes the glories of the Ganges River. The water of the Ganges is called patita-pāvanī, the deliverer of all sinful living beings. It is a proven fact that a person who regularly bathes in the Ganges is purified both externally and internally. Externally his body becomes immune to all kinds of disease, and internally he gradually develops a devotional attitude toward the Supreme Personality of Godhead. Throughout India, many thousands of people live on the banks of the Ganges, and by regularly bathing in her waters, they are undoubtedly being purified both spiritually and materially. Many sages, including Śaṅkarācārya, have composed prayers in praise of the Ganges, and the land of India itself has become glorious because such rivers as the Ganges, Yamunā, Godāvarī, Kāverī, Kṛṣṇā and Narmadā flow there. Anyone living on the land adjacent to these rivers is naturally advanced in spiritual consciousness. Śrīla Madhvācārya says:
vārāhe vāma-pādaṁ tu
tad-anyeṣu tu dakṣiṇam
pādaṁ kalpeṣu bhagavān
ujjahāra trivikramaḥ
Standing on His right foot and extending His left to the edge of the universe, Lord Vāmana became known as Trivikrama, the incarnation who performed three heroic deeds.
