While engaged with the brāhmaṇas who were too much involved in the performance of Vedic sacrifices, Kṛṣṇa and Balarāma also saw that the cowherd men were preparing a similar sacrifice in order to pacify Indra, the King of heaven, who is responsible for supplying water.
(Krsna Book).

The gopīs, being naturally very affectionate to Kṛṣṇa, began to offer Him yogurt mixed with their tears, and they poured incessant blessings upon Him. Mother Yaśodā, mother Rohiṇī, Nanda and Balarāma, who is the strongest of the strong, embraced Kṛṣṇa one after another and, from spontaneous feelings of affection, blessed Him over and over again.
(Krsna Book).

Once, when He was engaged in tending the calves in the forest along with His elder brother, Balarāma, a demon named Bakāsura appeared, and Kṛṣṇa at once bifurcated the demon's beak. When the demon known as Vatsāsura entered among the calves tended by Kṛṣṇa with a desire to kill Him, He immediately detected the demon, killed him and threw him into a tree. When Kṛṣṇa, along with His brother, Balarāma, entered the Tālavana forest, the demon known as Dhenukāsura, in the shape of an ass, attacked Them and was immediately killed by Balarāma, who caught his hind legs and threw him into a palm tree.
(Krsna Book).

Although the Dhenukāsura demon was assisted by his cohorts, also in the shape of asses, all were killed, and the Tālavana forest was then open for the use of the animals and inhabitants of Vṛndāvana. When Pralambāsura entered amongst Kṛṣṇa's cowherd boyfriends, Kṛṣṇa caused him to be killed by Balarāma. Thereafter, Kṛṣṇa saved His friends and cows from a severe forest fire, and He chastised the Kāliya serpent in the lake of the Yamunā River and forced him to leave the vicinity of the Yamunā; He thereby made the water of the Yamunā poisonless.”
(Krsna Book).

When Nanda Mahārāja was taken away by one of Varuṇa's servants, Nanda's companions began to call loudly for Kṛṣṇa and Balarāma. Immediately Kṛṣṇa and Balarāmacould understand that Nanda Mahārāja had been taken by a servant of Varuṇa. Thus They went to the abode of Varuṇa, for They were pledged to give protection to the inhabitants of Vṛndāvana, who were all unalloyed devotees of the Lord.
(Krsna Book).

Devotees, having no shelter other than the Supreme Personality of Godhead, naturally cry to Him for help, exactly like children who do not know anything but the protection of their parents. The demigod Varuṇa received Lord Kṛṣṇa and Balarāma with great respect and said, “My dear Lord, actually at this very moment, because of Your presence, my life as the demigod Varuṇa has become successful."
(Krsna Book).

"Dear banyan tree, have you seen the son of Mahārāja Nanda passing this way, laughing and playing on His flute? He has stolen our hearts and gone away. If you have seen Him, kindly inform us which way He has gone. Dear aśoka tree, dear nāga flower tree and campaka flower tree, have you seen the younger brother of Balarāma pass this way? He has disappeared because of our pride."
(Krsna Book).

O fortunate trees, we are thinking of Kṛṣṇa, the younger brother of Balarāma. While passing through here, with one hand resting on the shoulder of the goddess of fortune and the other hand twirling a lotus flower, He must have been very much pleased to accept your obeisances, and He must have glanced at you with great pleasure.
(Krsna Book).

Two gopīs imitated Kṛṣṇa and Balarāma, and many others imitated Their cowherd boyfriends. One gopī assumed the form of Bakāsura, and another forced her to fall down as the demon Bakāsura did when he was killed; similarly, another gopī defeated Vatsāsura.
(Krsna Book).

After this incident, on a very pleasant night Kṛṣṇa and His elder brother, Balarāma, who are inconceivably powerful, went into the forest of Vṛndāvana. They were accompanied by the damsels of Vrajabhūmi, and They began to enjoy their company. The young damsels of Vraja were very nicely dressed and anointed with pulp of sandalwood and decorated with flowers. The moon was shining in the sky, surrounded by glittering stars.
(Krsna Book).

The breeze was blowing, bearing the aroma of mallikā flowers, and the bumblebees were mad after the aroma. Taking advantage of the pleasing atmosphere, Kṛṣṇa andBalarāma began to sing very melodiously. The damsels became so absorbed in Their rhythmical song that they almost forgot themselves; their hair loosened, their clothes slackened, and their garlands began to fall to the ground.
(Krsna Book).

At that time, while Kṛṣṇa, Balarāma and the damsels were so much absorbed, almost in madness, a demoniac associate of Kuvera (the treasurer of the heavenly planets) appeared on the scene. The demon's name was Śaṅkhacūḍa because on his head there was a valuable jewel resembling a conchshell. Just as the two sons of Kuvera had been puffed up over their wealth and opulence and did not care for Nārada Muni's presence, this Śaṅkhacūḍa was also puffed up over material opulence. He thought that Kṛṣṇa and Balarāma were two ordinary cowherd boys enjoying the company of many beautiful girls.
(Krsna Book).

Generally, in the material world, a person with riches thinks that all beautiful women should be enjoyed by him. Śaṅkhacūḍa also thought that since he belonged to the rich community of Kuvera, he, not Kṛṣṇa and Balarāma, should enjoy the company of so many beautiful girls. He therefore decided to take charge of them. He appeared before Kṛṣṇa, Balarāmaand the damsels of Vraja and began to lead the girls away to the north. He commanded them as if he were their proprietor and husband, despite the presence of Kṛṣṇa and Balarāma.
(Krsna Book).

Being forcibly taken away by Śaṅkhacūḍa, the damsels of Vraja called out the names of Kṛṣṇa and Balarāma for protection. The two brothers immediately began to follow them, taking up big logs of śāla wood in Their hands. “Don’t be afraid, don’t be afraid,” They called to the gopīs. "We are coming at once to chastise this demon." Very quickly They reached Śaṅkhacūḍa. Thinking the brothers too powerful, Śaṅkhacūḍa left the company of the gopīs and ran in fear for his life. But Kṛṣṇa would not let him go. He entrusted the gopīs to the care of Balarāma and followed Śaṅkhacūḍa wherever he fled. Kṛṣṇa wanted to take the valuable jewel resembling a conchshell from the head of the demon. After following him a very short distance, Kṛṣṇa caught him, struck his head with His fist and killed him. He then took the valuable jewel and returned. In the presence of all the damsels of Vraja, He presented the valuable jewel to His elder brother, Balarāma.
