Lord Shiva gifted his famous bow to Dev vrata, who was a great devotee and the ancestor of King Janaka. This bow was extremely powerful and heavy and it was made by Lord Vishwakarma and gifted to Lord Shiva. King Janaka’s daughter Sita had lifted the bow once while playing with her sisters. This could not be done by anyone else in the kingdom, so Janaka was astonished. So King Janaka declared that Sita would be married only to a man who could lift and string the Shiva Dhanush.
