Dilipa

The ancestral chain Sagara – Asmanjas – Anshuman – Dilipa – Bhagiratha.

King Sagara had lost 60,000 sons who could only find salvation through the descent of Ganga.

Everyone in the ancestral chain tried hard – it was Bhagiratha who brought the Ganga to earth.

Ganga becomes Ganga in Devprayag, where the rivers Alaknanda and Bhagirathi converge.
