It is Shiva's relationship with Ganga, that is the best-known in Hinduism. Her descent is not a one time event, but a continuously occurring one in which she is forever falling from heaven into his locks and being forever tamed. Shiva, is depicted in Hindu iconography as Gangadhara, the "Bearer of the Ganga," with Ganga, shown as spout of water, rising from his hair. The Shiva-Ganga relationship is both perpetual and intimate. Shiva is sometimes called Uma-Ganga-Patiswara ("Husband and Lord of Uma (Parvati) and Ganga"), and Ganga often arouses the jealousy of Shiva's better-known consort Parvati.

Ganga is the shakti or the moving, restless, rolling energy in the form of which the otherwise recluse and unapproachable Shiva appears on earth. As water, this moving energy can be felt, tasted, and absorbed. The war-god Skanda addresses the sage Agastya in the Kashi Khand of the Skanda Purana in these words ~

"One should not be amazed, that this Ganges is really Power, for is she not the Supreme Shakti of the Eternal Shiva, taken in the form of water?
This Ganges, filled with the sweet wine of compassion, was sent out for the salvation of the world by Shiva, the Lord of the Lords.
Good people should not think this Triple-Pathed River to be like the thousand other earthly rivers, filled with water. "

The Ganges is invoked whenever water is used in Hindu ritual, and is therefore present in all sacred waters. In spite of this, nothing is more stirring for a Hindu than a dip in the actual river, which is thought to remit sins, especially at one of the famous tirthas such as Gangotri, Haridwar, Prayag, or Varanasi.

Jawaharlal Nehru asked for a handful of his ashes to be thrown into the Ganges. "The Ganga," he wrote in his will, "is the river of India, beloved of her people, round which are intertwined her racial memories, her hopes and fears, her songs of triumph, her victories and her defeats. She has been a symbol of India's age-long culture and civilization, ever-changing, ever-flowing, and yet ever the same Ganga." ✨👁💦🐍💦🔱💀🌊🌙🕉🐚🔔🌀💦✨
