Srimad Bhagvata Mahapurana: Book 10: Chapter 11: Verses 53-59
Relieved to find Him released from the mouth of Baka and returned to the sporting ground, the boys headed by Balarama embraced Him even as the senses would welcome life. Collecting the calves, they returned to Vraja and narrated the incident. Astonished to hear of it and greeted by Sri Krsna (who was most beloved of them), the cowherds and cowherdesses looked on Him with thirsty eyes out of eagerness as though he had returned from the land of the dead. (They said to one another,) "Oh, dear me ! there has been many a mortal enemy of this chap ! Evil has (however) befallen them alone inasmuch as terror was brought by them to others in a previous existence. Though terrible to look at, they are certainly not able to overpower Him all the same. Approaching him with intent to slay him they (on the other hand), perish like moths in fire. Ah, the words of the knowers of Brahma can never be untrue ! Whatever the worshipful Garga uttered has been fully verified." Thus recounting with joy the story of Sri Krsna and Balarama and rejoicing (over it), the cowherds headed by Nanda did not experience the agony of mundane life. In this way Balarama and Sri Krsna passed Their childhood in Vraja in childlike games, such as hide-and-seek, constructing toydams, and jumping over like monkeys.
Thus ends the eleventh discourse entitled The destruction of Vatsasura and Bakasura,' in the first half of Book Ten of the great and glorious Bhagavata-Purana, otherwise known as the Paramahamsa-Samhita.
