Balarāma inquired from Kṛṣṇa about the actual situation. He said, "My dear Kṛṣṇa, in the beginning I thought that all these calves and cowherd boys were either great sages and saintly persons or demigods, but at present it appears that they are actually Your expansions. They are all You; You Yourself are playing as the calves and boys. What is the mystery of this situation? Where have those other calves and boys gone? And why are You expanding Yourself as the calves and boys? Will You kindly tell Me what is the cause?" At the request of Balarāma, Kṛṣṇa briefly explained the whole situation: how the calves and boys were stolen by Brahmā and how He was concealing the incident by expanding Himself so people would not know that the original calves and boys were missing.
(Krsna Book).

While Kṛṣṇa and Balarāma were talking, Brahmā returned after a moment's interval (according to the duration of his life). We have information of Lord Brahmā’s duration of life from the Bhagavad-gītā: 1,000 times the duration of the four ages, or 1,000 x 4,320,000 years, constitute Brahmā’s twelve hours. Similarly, one moment of Brahmā’s time is equal to one year of our solar calculation. After one moment of Brahmā’s calculation, Brahmā came back to see the fun caused by his stealing the boys and calves. But he was also afraid that he was playing with fire. Kṛṣṇa was his master, and he had played mischief for fun by taking away His calves and boys.
(Krsna Book).

In this way, Kṛṣṇa consciousness was fully explained to Mahārāja Parīkṣit by Śukadeva Gosvāmī as he recited to the King the statements and prayers of Lord Brahmā. These descriptions of Lord Kṛṣṇa's pastimes with His cowherd boys, His eating with them on the bank of the Yamunā, and Lord Brahma's prayers unto Him are all transcendental subject matters. Anyone who hears, recites or chants them surely gets all his spiritual desires fulfilled. Thus Kṛṣṇa's childhood pastimes, His sporting with Balarāma and the cowherd boys in Vṛndāvana, were described.
(Krsna Book).

In this way Śrī Kṛṣṇa, along with His elder brother Balarāma, passed the childhood age known as kaumāra and stepped into the age of paugaṇḍa, from the sixth year up to the tenth. At that time, all the cowherd men conferred and agreed to give those boys who had passed their fifth year charge of the cows in the pasturing ground. Given charge of the cows, Kṛṣṇa and Balarāma traversed Vṛndāvana, purifying the land with Their lotus footprints.
(Krsna Book).

Accompanied by the cowherd boys and Balarāma, Kṛṣṇa brought forward the cows and played on His flute as He entered the forest of Vṛndāvana, which was full of flowers, vegetables and pasturing grass. The Vṛndāvana forest was as sanctified as the clear mind of a devotee and was full of bees, flowers and fruits. There were chirping birds and clear-water lakes, with waters that could relieve one of all fatigue. Sweet-smelling breezes blew always, refreshing the mind and body. Kṛṣṇa, with His friends and Balarāma, entered the forest and, seeing the favorable situation, desired to enjoy the atmosphere to the fullest extent. Kṛṣṇa saw all the trees, overloaded with fruits and fresh twigs, bending down to touch the ground as if welcoming Him by touching His lotus feet. He was very much pleased by the behavior of the trees, fruits and flowers, and He began to smile, realizing their desires.
(Krsna Book).

Kṛṣṇa then spoke to His elder brother Balarāma as follows: “My dear brother, You are superior to all of us, and Your lotus feet are worshiped by the demigods. Just see how these trees, full with fruits and flowers, have bent down to worship Your lotus feet. It appears that they are trying to get out of the darkness that has obliged them to accept the form of trees.
(Krsna Book).

In this way, Lord Kṛṣṇa and Balarāma began to enjoy the residents of Vṛndāvana to Their full satisfaction as They herded the calves and cows on the bank of the Yamunā. In some places Kṛṣṇa and Balarāma were accompanied by Their friends. The boys were singing, imitating the humming sound of the drones and accompanying Kṛṣṇa and Balarāma, who were garlanded with forest flowers. While walking, the boys sometimes imitated the quacking sound of the swans in the lakes, or when they saw the peacocks dancing, they imitated them before Kṛṣṇa. Kṛṣṇa also moved His neck, imitating the dancing and making His friends laugh.
(Krsna Book).

The cows taken care of by Kṛṣṇa had different names, and Kṛṣṇa would call them with love. After hearing Kṛṣṇa calling, the cows would immediately respond by mooing, and the boys would enjoy this exchange to their hearts' content. They would all imitate the sound vibrations made by the different kinds of birds, especially the cakoras, peacocks, cuckoos and bhāradvājas. Sometimes, when they would see the weaker animals fleeing out of fear of the sounds of tigers and lions, the boys, along with Kṛṣṇa and Balarāma, would imitate the animals and run away with them. When they felt some fatigue, they would sit down, and Balarāma would put His head on the lap of one of the boys just to take rest, and Kṛṣṇa would immediately come and begin massaging the legs of Balarāma. And sometimes Kṛṣṇa would take a palm fan and fan the body of Balarāma, causing a pleasing breeze to relieve Him of His fatigue. Other boys would sometimes dance or sing while Balarāma took rest, and sometimes they would wrestle amongst themselves or jump. When the boys were thus engaged, Kṛṣṇa would immediately join them, and catching their hands, He would enjoy their company and laugh and praise their activities.
(Krsna Book).

While Kṛṣṇa was thus engaged in His transcendental pastimes, exhibiting His internal potency in the company of the supermost fortunate cowherd boys, there occurred another chance for Him to exhibit the superhuman powers of Godhead. His most intimate friends Śrīdāmā, Subala and Stoka Kṛṣṇa addressed Kṛṣṇa and Balarāma with great love and affection thus: “Dear Balarāma, You are very powerful; Your arms are very strong.
(Krsna Book).

Dear Kṛṣṇa and Balarāma, this demon is present there in the form of an ass, and he is surrounded by similar demon friends who have assumed the same shape. All of them are very strong, so it is very difficult to approach this place. Dear brothers, You are the only persons who can kill such demons. Other than You, no one can go there for fear of being killed. Not even animals go there, and no birds are living there; they have all left. One can only appreciate the sweet aroma that is coming from that place. It appears that up until now, no one has tasted the sweet fruits there, either on the tree or on the ground. Dear Kṛṣṇa, to tell You frankly, we are very attracted by this sweet aroma. Dear Balarāma, if You like, let us all go there and enjoy these fruits. The aroma of the fruits is now spread everywhere. Don’t You smell it from here?”
(Krsna Book).
