The Seventeenth Chapter describes the origin of the Ganges River and how it flows in and around Ilāvṛta-varṣa. There is also a description of the prayers Lord Śiva offers to Lord Saṅkarṣaṇa, part of the quadruple expansions of the Supreme Personality of Godhead. Lord Viṣṇu once approached Bali Mahārāja while the King was performing a sacrifice. The Lord appeared before him as Trivikrama, or Vāmana, and begged alms from the King in the form of three steps of land. With two steps, Lord Vāmana covered all three planetary systems and pierced the covering of the universe with the toes of His left foot. A few drops of water from the Causal Ocean leaked through this hole and fell on the head of Lord Śiva, where they remained for one thousand millenniums. These drops of water are the sacred Ganges River. It first flows onto the heavenly planets, which are located on the soles of Lord Viṣṇu’s feet. The Ganges River is known by many names, such as the Bhāgīrathī and the Jāhnavī. It purifies Dhruvaloka and the planets of the seven sages because both Dhruva and the sages have no other desire than to serve the Lord’s lotus feet.
