1-4. 0 sages, listen ye all. O brahmins, may the other activities of Bala the powerful be heard.
There was a monkey of great prowess named Dvivida. He was a friend of Naraka the leader of Asuras, one who was opposed to Devas. That powerful monkey nursed continuous animosity towards Devas.
Dvivida said:
Krishna killed Naraka who was proud of his strength. Hence I shall take revenge on all Devas.
Vyāsa said:
5-10. He destroyed Yajñas and annihilated men. Deluded by ignorance he danned and demolished sacrificial rites. He violated bounds of decency. He destroyed embodied beings. The fickle fellow burnt territories, cities and villages. At places he hurled mountains and powdered villages. He uprooted mountains and hurled them into oceans. Standing in the middle of the ocean he made it agitated. Thereby, O brahmins, the ocean was excessively stirred up and it overflew the shores, flooding the villages and cities nearby. He used to assume different forms as he pleased and crushed down plants and trees as he wandered here and there. The monkey reduced everything to powder. This entire universe was thus ruined and ravaged by that wicked monkey.
11-14. O brahmins, self-study of the Vedas and repetition of the Vasatkāra Mantras ceased. Everyone was extremely miserable.
Once Balarama, the highly blessed Revati and other excellent ladies were seated in the Raivata garden and engaged in drinking wine. Elegant ladies were singing in the midst of highly elegant and charming assembly. The chief and the most excellent among the descendants of Yadu sported like Kubera on the Mandara mountain.
At that time the monkey came there, seized the plough-share and the threshing rod of Balarama and began to emulate him standing in front of him. The monkey stood in front of the womenfolk also and chattered and laughed.
15-20. He struck and hit the bowls and jugs filled with beverages. Thereupon Bala, with great fury surging up in his soul, rebuked him. In spite of that the monkey disregarded him and made tinkling chattering noise. Thereat, Bala got up in anger and seized his iron club. The excellent monkey seized a terrible rocky boulder, and hurled it (against Bala). The most excellent Yadava split it into a thousand bits by his iron club. The rocky boulder fell on the Earth. The monkey dodged the iron club and fell down. On getting up in great anger and gathering up his strength he struck him on his chest. Then the monkey was hit on his head with his fist by Bala. Thereupon Dvivida vomited blood and fell down. His life became extinct. As his body fell down the peak of the mountain crumbled.
21-23. Osages, the peak split into a hundred pieces as though it had been struck down by the thunder-bolt of Indra. Then Devas discharged showers of flowers over Rāma. They approached him and praised him "Well done. A great task has been accomplished. O heroic one, the universe had been harassed by this wicked monkey who used to render help unto asuras. Fortunately, he has been destroyed."
Vyāsa said:
Thus the activities of Balarama, the incarnation of Sesa, the supporter of the Earth, cannot be measured and stipulated. There were many.
Summary of chapter 100 of the Brahma Purana is as follows:
The powerful ape Dvivida — a friend of Naraka who had vowed revenge against Kṛṣṇa — terrorizes the land, uprooting mountains, destroying forests, and harassing human settlements. He comes to disturb Balarāma's sporting with companions. Balarāma, angry, fights the ape in a furious battle and slays him with his ploughshare, removing a long-standing threat to the world's peace.
