While taking charge of the calves, sometimes the two brothers played on Their flutes. And sometimes They played with āmalakī fruits and bael fruits, just like small children play with balls. Sometimes They danced and made tinkling sounds with Their ankle bells. Sometimes They made Themselves into bulls and cows by covering Themselves with blankets. Thus Kṛṣṇa and Balarāma played. The two brothers also used to imitate the sounds of bulls and cows and play at bullfighting. Sometimes They used to imitate the sounds of various animals and birds. In this way, They enjoyed Their childhood pastimes apparently like ordinary, mundane children.
