Dressed in blue and yellow garments, and anointed with fragrant unguents, Keśava and Ráma proceeded to the hall of arms, which was hung round with garlands. Inquiring of the warders which bow he was to try, and being directed to it, he took it, and bent it; but drawing it with violence, he snapped it in two, and all Mathurá resounded with the noise which its fracture occasioned. Abused by the warders for breaking the bow, Krishńa and Ráma retorted, and defied them, and left the hall.
