Legend has it that Sage Vasishta’s holy cow Nandini once
fell into a deep gorge. The cow could not free itself. The sage then requested
Lord Shiva to help. Shiva then directed Saraswati River
to flood the gorge so that Nandini can float up.
Once Nandini was saved, Sage Vasishta decided to permanently
fill the gorge so that such mishaps do not happen in future. The sage then
requested the youngest son of Himalaya , king
of mountains, to fill the gorge permanently.
The son of Himalaya took
the help of a might snake named Arbud to fill the gorge. When they filled the
gorge a mountain peak formed and the spot was called Mount Arbud .
The name later changed to Mount
Abu .
