so'nveṣamāṇaḥ kaunteyānpāñcālyo janamejaya |

"Yajnasena always cherished the desire of bestowing his daughter on Kiriti (Arjuna), the son of Pandu. But he never spoke of it to anybody. And, O Janamejaya, the king of Panchala thinking of Arjuna caused a very stiff bow to be made that was incapable of being bent by any except Arjuna. Causing some machinery to be erected in the sky, the king set up a mark attached to that machinery. And Drupada said, 'He that will string this bow and with these well-adorned arrows shoot the mark above the machine shall obtain my daughter.'
