The Legend:
King of Sialkot marries a young girl Loona. She falls for his son (from 1st wife) Puran who is of her age. He declines her advances; she complains abt him; he's punished (hands/feet amputated and thrown into a well). A guru rescues him; he gets well and becomes a Bhagat. Years later, Loona still childless comes to "the Bhagat". The truth comes out; she admits her mistake; he forgives them and wishes a child, Rasalu.
