The grandsire, too, excited with rage, is ready to slaughter the Panchalas. For protecting them Phalguni is battling with the foe. O thou of mighty arms hearing now of these two tasks, both of which demand prompt attention, go and give succour to Hidimva's son who is placed in a position of very great danger.' Listening to these words of his brother, Vrikodara, with great speed, proceeded, frightening all the kings with his leonine roars, with great impetuosity, O king, like the ocean itself during the period of the new full moon. Him followed Satyadhriti and Sauchiti difficult of being vanquished in battle, and Srenimat, and Vasudana and the powerful son of the ruler of Kasi, and many car-warriors headed by Abhimanyu, as also those mighty car-warriors, viz., the sons of Draupadi, and the valiant Kshatradeva, and Kshatradharman, and Nila, the ruler of the low countries, at the head of his own forces. And these surrounded the son of Hidimva with a large division of cars (for aiding him). And they advanced to the rescue of Ghatotkacha, that prince of the Rakshasas, with the six thousand elephants, always infuriate and accomplished in smiting. And with their loud leonine roars, and the clatter of their car-wheels, and with the tread of their horse's hoofs, they made the very earth to tremble. Hearing the din of those advancing warriors the faces of thy troops who were filled with anxiety in consequence of their fear of Bhimasena became pale.
