The souls of the sons of Sagara wandered as ghosts since their final rites had not been performed.

The souls of the sons of Sagara wandered as ghosts since their final rites had not been performed. For the moksha of all the sons of Sagar, Anshuman(nephew of those 60,000 son) started to pray Brahma to bring Ganga to the earth till the end of his life, but was not successful. Then his son Dilip did the same but did not succeed. When Bhagiratha (Means, one who does great hard work- he got his name from his great hard work for bringing Ganga to earth), one of the descendants of Sagara, son of Dilip, learnt of this fate, he vowed to bring Ganga down to Earth so that her waters could cleanse their souls and release them to heaven.
Bhagiratha prayed to Brahma that Ganga come down to Earth. Brahma agreed and he ordered Ganga to go down to the Earth and then on to the nether regions so that the souls of Bhagiratha's ancestors would be able to go to heaven. Ganga would have swept the whole Earth away as she fell from the heavens. Alarmed, Bhagiratha prayed to Shiva that he break up Ganga's descent.

Ganga arrogantly fell on Shiva's head. But Shiva calmly trapped her in his hair and let her out in small streams. The touch of Shiva further sanctified Ganga. As Ganga travelled to the nether-worlds, she created a different stream to remain on Earth to help purify unfortunate souls there. She is the only river to follow from all the three worlds – Swarga (heaven), Prithvi (Earth) and Patala (netherworld or hell). Thus is called Tripathaga (one who travels the three worlds) in Sanskrit language.

Because of Bhagiratha's efforts, Ganga descended to Earth and hence the river is also known as Bhagirathi and the term Bhagirath prayatna is used to describe valiant efforts or difficult achievements.

Ganga means knowledge; knowledge that purifies your soul. Head is always the symbol of knowledge. Heart is the symbol of love.
If Ganga were to be love, it should have come out of the heart of Lord Shiva. It is coming out of the head, because it simply means knowledge.

Knowledge is liberating, knowledge brings freedom, knowledge is purifying. All these are the characteristics of knowledge. Knowledge is also movement; motion. So Ganga (knowledge) has to come out of Lord Shiva’s (the divinity’s) head.! ✨🌊👁🏞🌀🕉🙏
