Srimad Bhagvata Mahapurana: Book 10: Chapter 18: Verses 27-32
Balarama (the wielder of a plough for a weapon) felt a bit afraid to perceive that body soaring in the skies at a great speed with burning eyes and hair glowing as flames and with its fearful tusks reaching the end of its contracted eye-brows and looking uncanny with the splendour of its bracelets, coronet and ear-rings. Balarama, to whom self-consciousness (the knowledge of His divinity) had returned the very next moment and who had (consequently) been rid of (all) fear, hit the enemy- who was carrying him through the sky as though it were some treasure found by him-in (great) rage on his head with his strong fist, which descended with the vehemence of a thunderbolt, even as Indra (the ruler of the gods) would strike a mountain. With his head smashed forthwith and deprived of his consciousness when struck (by Balarama), and vomiting blood, the said demon fell dead, uttering a loud cry, as a mountain struck with the weapon of Indra. Seeing Pralamba slain by the mighty Balarama, the cowherds felt highly amazed and shouted, "Well done, Bravo !' Uttering benedictions on him and embracing him as though he had returned to life after death, they extolled him, deserving as he was of such praise, their mind overwhelmed with affection. Supremely gratified on the sinful Pralamba having been slain, the gods covered Bala with flowers and applauded him exclaiming, "Well done ! Bravo !"
Thus ends the eighteenth discourse entitled The Lord slays Pralamba,' in the first half of Book Ten of the great and glorious Bhagavata-Purana, otherwise known as the Paramahamsa Samhita.
