"In this way, both Lord Kṛṣṇa and Balarāma began to enjoy the residents of Vṛndāvana to Their full satisfaction, along with the calves and cows on the bank of the Yamunā. In some places both 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.
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, cuckoo 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 He 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. When Kṛṣṇa would feel tired and fatigued, He would sometimes take shelter of the root of a big tree, or the lap of a cowherd boy, and lie down. When He would lie down with a boy or a root as His pillow, some of the boys would come and massage His legs, and some would fan His body with a fan made from leaves. Some of the more talented boys would sing in very sweet voices to please Him. Thus very soon His fatigue would go away. The Supreme Personality of Godhead, Kṛṣṇa, whose legs are tended by the goddess of fortune, shared Himself with the cowherd boys as one of them, expanding His internal potency to appear exactly like a village boy. But despite His appearing just like a village boy, there were occasions when He proved Himself to be the Supreme Personality of Godhead. Sometimes men pose themselves as the Supreme Personality of Godhead and cheat innocent people, but they can only cheat; they cannot exhibit the potency of God."
