While Lord Balarāma was absent in Vṛndāvana, this King Pauṇḍraka, the King of the Karūṣa Province, being foolish and puffed up, sent a messenger to Lord Kṛṣṇa. Lord Kṛṣṇa is accepted as the Supreme Personality of Godhead, but King Pauṇḍraka directly challenged Kṛṣṇa through the messenger, who stated that Pauṇḍraka, not Kṛṣṇa, was Vāsudeva.
(Krsna Book).

While Śukadeva Gosvāmī continued to speak on the transcendental pastimes and characteristics of Lord Kṛṣṇa, King Parīkṣit, upon hearing him, became more and more enthusiastic and wanted to hear further. Śukadeva Gosvāmī next narrated the story of Dvivida, the gorilla who was killed by Lord Balarāma.
(Krsna Book).

While creating such great disturbances all over the country, sometimes he heard very sweet musical sounds from Raivataka Mountain, and so he entered that mountainous region. There he saw Lord Balarāma in the midst of many beautiful young girls, enjoying their company while singing and dancing. He became captivated by the beauty of Lord Balarāma's body, whose every feature was very beautiful, decorated as He was with a garland of lotus flowers. Similarly, all the young girls present, dressed and garlanded with flowers, exhibited much beauty. Lord Balarāma seemed fully intoxicated from drinking the vāruṇī beverage, and His eyes appeared to be rolling in a drunken state. Lord Balarāma appeared just like the king of the elephants in the midst of many she-elephants.
(Krsna Book).

This gorilla by the name Dvivida could climb up into the trees and jump from one branch to another. Sometimes he would jerk the branches, creating a particular type of sound—kilakilā—so that Lord Balarāma was greatly distracted from the pleasing atmosphere. Sometimes Dvivida would come before the women and exhibit different types of caricatures. By nature young women are apt to enjoy everything with laughter and joking, and when the gorilla came before them they did not take him seriously but simply laughed at him. However, the gorilla was so rude that even in the presence of Balarāma he began to show the lower part of his body to the women, and sometimes he would come forward to show his teeth while moving his eyebrows. He disrespected the women, even in the presence of Balarāma.
(Krsna Book).

Lord Balarāma's name suggests not only that He is very powerful but that He takes pleasure in exhibiting extraordinary strength. So He took a stone and threw it at Dvivida. The gorilla, however, artfully avoided being struck by the stone. In order to insult Balarāma, the gorilla took away the earthen pot in which the vāruṇī was kept. Dvivida, being thus intoxicated with his limited strength, began to tear off all the valuable clothes worn by Balarāma and the accompanying young girls. He was so puffed up that he thought Balarāma could not do anything to chastise him, and he continued to offend Balarāmajī and His companions.
(Krsna Book).

When Lord Balarāma saw the disturbances created by the gorilla and heard that he had already performed many mischievous activities all over the country, He became very angry and decided to kill him. Immediately He took His club in His hands. The gorilla could understand that now Balarāma was going to attack him. To counteract Balarāma, he immediately uprooted a big oak tree, and with great force he came and struck Lord Balarāma's head. Lord Balarāma, however, immediately caught hold of the big tree and remained undisturbed, just like a great mountain. To retaliate, He took His club, named Sunanda, and hit the gorilla with it, severely injuring his head. Currents of blood flowed from the gorilla's head with great force, but the stream of blood simply enhanced his beauty, like a stream of liquid manganese coming out of a great mountain.
(Krsna Book).

The striking of Balarāma's club did not even slightly disturb him. On the contrary, he immediately uprooted another big oak tree and, after clipping off all its leaves, again struck Balarāma's head with it. But Balarāma, with the help of His club, tore the tree to pieces. Since the gorilla was very angry, he took another tree in his hands and struck LordBalarāma's body. Again Lord Balarāma tore the tree to pieces, and the fighting continued. Each time the gorilla would bring out a big tree to strike Balarāma, Lord Balarāma would tear the tree to pieces by the striking of His club, and the gorilla Dvivida would clutch another tree from another direction and again attack Balarāma in the same way. As a result of this continuous fighting, the forest became treeless. When no more trees were available, Dvivida took help from the hills and threw large pieces of stone, like rainfall, upon the body of Balarāma.
(Krsna Book).

Lord Balarāma, in a great sporting mood, began to smash those big pieces of stone into mere pebbles. The gorilla, being bereft of all trees and stone slabs, now stood before Balarāma and waved his strong fists. Then, with great force, he began to beat Lord Balarāma's chest with his fists. This time Lord Balarāma became most angry. Since the gorilla was striking Him with his hands, Lord Balarāma would not strike him back with His own weapons, the club or the plow. Simply with His fists He struck the collarbone of the gorilla. This blow proved fatal to Dvivida, who immediately vomited blood and fell unconscious upon the ground. When the gorilla fell, all the hills and forests appeared to totter.
(Krsna Book).

After this horrible incident, all the Siddhas, great sages and saintly persons from the upper planetary system showered flowers on the person of Lord Balarāma and vibrated sounds glorifying His supremacy. All of them chanted, "All glories to Lord Balarāma! Let us offer our respectful obeisances unto Your lotus feet. By killing this great demon, Dvivida, You have initiated an auspicious era for the world." All such jubilant sounds of victory were heard from outer space. After killing the great demon Dvivida and being worshiped by showers of flowers and glorious sounds of victory, Balarāma returned to His capital city, Dvārakā.
(Krsna Book).

Although Lord Balarāma knew very well that by slight provocation people are prepared to fight with one another in the Age of Kali, He did not like the idea that the two great dynasties, the Kuru dynasty and the Yadu dynasty, would fight amongst themselves, even though they were influenced by Kali-yuga. "Instead of fighting with them," He wisely thought, "let Me go there and see the situation, and let Me try to see if the fight can be settled by mutual understanding." Balarāma's idea was that if the Kuru dynasty could be induced to release Sāmba along with his wife, Lakṣmaṇā, then the fight could be avoided. He therefore immediately arranged for a nice chariot to go to Hastināpura, accompanied by learned priests and brāhmaṇas, as well as by some of the elder members of the Yadu dynasty. He was confident that the members of the Kuru dynasty would agree to this marriage and avoid fighting with the Yadus.
(Krsna Book).

As Lord Balarāma proceeded toward Hastināpura in His chariot, accompanied by the brāhmaṇas and elders, He looked like the moon shining in the clear sky amongst the glittering stars. When Lord Balarāma reached the precincts of the city of Hastināpura, He did not enter but stationed Himself in a camp outside the city, in a small garden house. Then He asked Uddhava to meet with the leaders of the Kuru dynasty and inquire from them whether they wanted to fight with the Yadu dynasty or to make a settlement. Uddhava went to see the leaders of the Kuru dynasty, and he met all the important members, including Bhīṣmadeva, Dhṛtarāṣṭra, Droṇācārya, Duryodhana and Bāhlika. After offering them due respects, he informed them that Lord Balarāma had arrived at the garden outside the city gate.
(Krsna Book).

The leaders of the Kuru dynasty, especially Dhṛtarāṣṭra and Duryodhana, were joyful because they knew very well that Lord Balarāma was a great well-wisher of their family. There were no bounds to their joy on hearing the news, and so they immediately welcomed Uddhava. In order to properly receive Lord Balarāma, they all took in their hands auspicious paraphernalia for His reception and went to see Him outside the city gate. According to their respective positions, they welcomed Lord Balarāma by giving Him in charity nice cows and arghya (a mixture of ārati water and an assortment of items such as honey, butter, flowers and sandalwood pulp). Because all of them knew the exalted position of Lord Balarāmaas the Supreme Personality of Godhead, they bowed their heads before the Lord with great respect. They all exchanged words of reception by asking one another about their welfare, and when such formalities were finished, Lord Balarāma, in a great voice and very patiently, submitted before them the following words for their consideration: “My dear friends, this time I have come to you as a messenger with the order of the all-powerful King Ugrasena.
(Krsna Book).

When Lord Balarāma spoke in a commanding tone full of heroic assertion, supremacy and chivalry, the leaders of the Kuru dynasty did not appreciate His statements. Rather, all of them became agitated, and with great anger they said, “Oh! These words are very astonishing but quite befitting the Age of Kali; otherwise how could Balarāma speak so vituperatively? The language and tone used by Balarāma are simply abusive, and due to the influence of this age it appears that the shoes befitting the feet want to rise to the top of the head, where the helmet is worn.
(Krsna Book).

Actually the members of the Kuru dynasty were very much puffed up due to their opulence, kingdom, aristocracy, family tradition, great warriors, family members and vast, expansive empire. They did not even observe common formalities of civilized society, and in the presence of Lord Balarāma they uttered insulting words about the Yadu dynasty. Having spoken in this unmannerly way, they returned to their city of Hastināpura.
(Krsna Book).

Although Lord Balarāma patiently heard their insulting words and simply observed their uncivil behavior, from His appearance it was clear that He was burning with anger and was thinking of retaliating with great vengeance. His bodily features became so much agitated that it was difficult for anyone to look at Him. He laughed very loudly and said, "It is true that if a man becomes too much puffed up because of his family, opulence, beauty and material advancement, he no longer wants a peaceful life but becomes belligerent toward all others. It is useless to give such a person good instruction for gentle behavior and a peaceful life; on the contrary, one should search out the ways and means to punish him."
(Krsna Book).

If I do not take steps against them, it will be improper on My part. Therefore, on this very day I shall rid the whole world of any trace of the Kuru dynasty. I shall finish them off immediately!” While talking like this, Lord Balarāma seemed so furious that He looked as if He could burn the whole cosmic creation to ashes. He stood up steadily and, taking His plow in His hand, began striking the earth with it, separating the whole city of Hastināpura from the earth, and then He began to drag the city toward the flowing water of the river Ganges. This caused a great tremor throughout Hastināpura, as if there had been an earthquake, and it seemed that the whole city would be dismantled.
