appears in the story of Ganga
. When Ganga came to earth after being released from lord Shiva's
locks, her torrential waters wreaked havoc with Jahnu's fields and penance. Angered by this, the great sage drank up all of Ganga's waters to punish her. Seeing this, the Gods prayed to the sage to release Ganga, so that she could proceed on her mission to release the souls of the ancestors of Bhagiratha. Jahnu relented and he released Ganga from his ear. For this, the Ganga
river is also known as Jahnvi
, meaning "daughter of Jahnu".
