When Balarāma and Kṛṣṇa were thus petitioned by Their intimate friends, They were inclined to please them, and with smiling faces They proceeded toward the forest, surrounded by all Their friends. Immediately upon entering the Tālavana, Balarāma began to yank the trees with His arms, exhibiting the strength of an elephant. Because of this jerking, all the ripe fruits fell down on the ground. Upon hearing the sound of the falling fruits, the demon Dhenukāsura, who was living there in the form of an ass, approached with great force, shaking the whole field so that all the trees moved as if there were an earthquake. The demon appeared before Balarāma and kicked His chest with his hind legs. At first Balarāma did not say anything, but with great anger the demon kicked Him again more vehemently. This time Balarāma immediately caught hold of the legs of the ass with one hand and, wheeling him around, threw him into the treetops. While he was being wheeled around by Balarāma, the demon lost his life. Balarāma threw the demon into the biggest palm tree about, and the demon's body was so heavy that the palm tree fell upon other trees, and several fell down. It appeared as if a great hurricane was passing through the forest, and all the trees were falling down, one after another. This exhibition of extraordinary strength is not astonishing because Balarāma is the Personality of Godhead known as Ananta Śeṣa Nāga, who is holding all the planets on the hoods of His millions of heads. He maintains the whole cosmic manifestation exactly as horizontal and vertical threads hold the weaving of a cloth.
(Krsna Book).

After the demon had been thrown into the trees, all the friends and associates of Dhenukāsura immediately assembled and attacked Balarāma and Kṛṣṇa with great force. They were determined to retaliate and avenge the death of their friend. But Kṛṣṇa and Balarāma caught each of the asses by the hind legs and, exactly in the same way, wheeled them around. Thus They killed all of them and threw them into the palm trees. Because of the dead bodies of the asses, there was a panoramic scene. It appeared as if clouds of various colors were assembled in the trees. Hearing of this great incident, the demigods from the higher planets showered flowers on Kṛṣṇa and Balarāma and beat their drums and offered devotional prayers.
(Krsna Book).

A few days after the killing of Dhenukāsura, people began to come into the Tālavana forest to collect the fruits, and animals began to return without fear to feed on the nice grasses growing there. Just by chanting or hearing these transcendental activities and pastimes of the brothers Kṛṣṇa and Balarāma, one can amass pious activities.
(Krsna Book).

When Kṛṣṇa and Balarāma entered the village of Vṛndāvana along with Their friends, They played Their flutes, and the boys praised Their uncommon activities in the forest. Their faces were decorated with tilaka and smeared with the dust raised by the cows, and Kṛṣṇa's head was decorated with a peacock feather. Both He and Balarāma played Their flutes, and the young gopīs were joyous to see Kṛṣṇa returning home. All the gopīs in Vṛndāvana remained very morose on account of Kṛṣṇa's absence. All day they were thinking of Kṛṣṇa in the forest or of Him herding cows in the pasture. When they saw Kṛṣṇa returning, all their anxieties were immediately relieved, and they began to look at His face the way drones hover over the honey of the lotus flower. When Kṛṣṇa entered the village, the young gopīs smiled and laughed. Kṛṣṇa, while playing the flute, enjoyed the beautiful smiling faces of the gopīs.
(Krsna Book).

Then Kṛṣṇa and Balarāma were immediately received by Their affectionate mothers, Yaśodā and Rohiṇī, who, according to the time's demands, began to fulfill the desires of their affectionate sons. Simultaneously, the mothers rendered service and bestowed benediction upon their transcendental sons. They took care of their children by bathing Them and dressing Them very nicely. Kṛṣṇa was dressed in yellowish garments, and Balarāma was dressed in bluish garments, and They were given all sorts of ornaments and flower garlands. Being relieved of the fatigue of Their day's work in the pasturing ground, They looked refreshed and very beautiful.
(Krsna Book).

They were given palatable dishes by Their mothers, and They pleasantly ate everything. After eating, They were seated nicely on clean bedding, and the mothers began to sing various songs of Their activities. As soon as They lay down on the bedding, They very quickly fell fast asleep. In this way, Kṛṣṇa and Balarāma used to enjoy Vṛndāvana life as cowherd boys.
(Krsna Book).

Sometimes Kṛṣṇa used to go with His boyfriends and Balarāma, and sometimes He used to go alone with His friends to the bank of the Yamunā and tend the cows. Gradually, the summer season arrived, and one day, while in the field, the boys and cows became very thirsty and began to drink the water of the Yamunā. The river, however, had been made poisonous by the venom of the great serpent known as Kāliya.
(Krsna Book).

While this scene was taking place on the bank of the Yamunā, there were ill omens manifest. The earth trembled, meteors fell from the sky, and the left side of men's bodies shivered. All these are indications of great immediate danger. Observing the inauspicious signs, the cowherd men, including Mahārāja Nanda, became very anxious out of fear. At the same time they were informed that Kṛṣṇa had gone to the pasturing ground without His elder brother, Balarāma. As soon as Nanda and Yaśodā and the cowherd men heard this news, they became even more anxious. Out of their great affection for Kṛṣṇa, and being unaware of the extent of His potencies, they became overwhelmed with grief and anxiety because they had nothing dearer than Kṛṣṇa and because they had dedicated their everything—life, property, affection, mind and activities—to Kṛṣṇa. Because of their great attachment for Kṛṣṇa, they thought, "Today Kṛṣṇa is surely going to be vanquished!"
(Krsna Book).

All the inhabitants of Vṛndāvana came out of the village to see Kṛṣṇa. The assembly consisted of children, old men, women, animals and all living entities; they knew that Kṛṣṇa was their only means of sustenance. While this was happening, Balarāma, who is the master of all knowledge, stood there simply smiling. He knew how powerful His younger brother was and that there was no cause for anxiety when Kṛṣṇa was fighting with an ordinary serpent of the material world. He did not, therefore, personally take any part in their sorrow. On the other hand, all the inhabitants of Vṛndāvana, being disturbed, began to search out Kṛṣṇa by following the impression of His footprints on the ground, and thus they moved hastily toward the bank of the Yamunā.
(Krsna Book).

Finally, by following the footprints marked with flag, bow and conchshell, the inhabitants of Vṛndāvana arrived at the riverbank and saw that all the cows and boys were weeping to behold Kṛṣṇa enwrapped in the coils of the black serpent. Then they became still more overwhelmed with grief. While Balarāma was smiling to see their lamentation, all the inhabitants of Vrajabhūmi merged into the ocean of grief because they thought that Kṛṣṇa was finished. Although the residents of Vṛndāvana did not know much about Kṛṣṇa, their love for Him was beyond comparison.
