According to mythology, Goddess Ganga, the daughter of heaven, manifested herself in the form a river to absolve the sins of king Bhagirath's predecessors, following his severe penance of 5500 years. Lord Shiva received into his matted locks to minimize the impact of her fall. The river itself begins at Gangotri which literally means Ganga Uttari or Ganga descending She came to be called Bhagirathi at her legendary source.

According to mythology King Sagar after slaying the demons on earth staged an Aswamedh Yagna to proclaim his supremacy. The King's 60,000 sons born of Queen Sumati and one son Asamanjas of Queen Kesani were to accompany the horse. Lord Indra fearing loss of his supremacy stole the horse and tied it to the ashram of ancient sage Kapil who was then deep into meditation. On their search for horse, the 60,000 sons stormed the ashram of Kapil and just before the attack on him the sage opened his eyes and reduced all the 60,000 sons of King Sagar except Asamanjas to ashes. King Sagar's grandson Anshuman was successful in recovering the horse from Kapil and was told that those 60,000 burnt will attain heavenly adobe if Ganga is brought down from heaven & their ashes were sleaned by its water. Then the great task of bringing Ganga to earth started. Anshuman failed and so did his son Dilip but his grandson Bhagirath succeeded.

The intense meditation made Ganga to descend from heaven and in order that the earth is not flooded, it remained suspended in the Coils of Lord Shiva's hair. Shiva pleased with King Bhagirath, released Ganga in seven streams - the most sacred streams - the most sacred streams on earth came to be known as Bhagirathi. King Sagar's 60,000 sons' ashes were touched with Ganga water and thus they were bestowed with eternal rest in heaven.
