"Sanjaya continued, 'Thus addressed, the son of Drona replied unto the king, who was invincible in battle, saying, "Arise, O king, blessed be thou, we shall yet vanquish the foe! I swear by all my religious acts, by all the gifts I have made, by truth itself, and my silent meditations, O king, that I shall today slay the Somakas!

Recollecting the words that the son of Pandu had said, those hunters, O king, whisperingly said unto one another, "We will discover Duryodhana (unto the Pandavas). The son of Pandu will then give us wealth!
