samavāye tato rājñāṃ kanyāṃ bhartṛsvayaṃvarām |

After a while, Arjuna obtained the virgin Krishna at the swayamvara, in the midst of a concourse of Rajas, by performing a very difficult feat of archery. And from this time he became very much respected in this world among all bowmen; and in fields of battle also, like the sun, he was hard to behold by foe-men. And having vanquished all the neighbouring princes and every considerable tribe, he accomplished all that was necessary for the Raja (his eldest brother) to perform the great sacrifice called Rajasuya.
