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.
The Ganges River, emanating from the lotus feet of the Lord, inundates the heavenly planets, especially the moon, and then flows through Brahmapurī atop Mount Meru. Here the river divides into four branches (known as Sītā, Alakanandā, Cakṣu and Bhadrā), which then flow down to the ocean of salt water. The branch known as Sītā flows through Śekhara-parvata and Gandhamādana-parvata and then flows down to Bhadrāśva-varṣa, where it mixes with the ocean of salt water in the West. The Cakṣu branch flows through Mālyavān-giri and, after reaching Ketumāla-varṣa, mixes with the ocean of salt water in the West.
