Sagara, sage Kapila told Anshuman that the waters of Ganga, who was

Ganga on earth. To bear the impact of the severity of the fall of River
Ganga, Bhagiratha prayed to Lord Shiva, who agreed for the same.

followed. They finally reached the spot where the ashes of the six
thousand sons lay and liberated the souls.
