te sva-prayasam vitatham niriksya
harav abhakta hata-yuddha-darpah
patim manas te dadhur atta-sarah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The asuras, who are never devotees of Lord Krsna, the Supreme Personality of Godhead, lost their pride in fighting when they found all their endeavors futile. Leaving aside their leader even in the very beginning of the fight, they decided to flee because all their prowess had been taken away by the enemy.
