That was children's sport, to go to the forest, take the calves and cows and carry some tiffin. Eat there, dance there, play there, and again come in the evening. Then they will take bath and change their dress and take their meals and immediately go to sleep. This was the boy's, children's, engagement. So how they would grow healthy, because they go outside and play and work, and very happily they enjoy the company. So there is no question of becoming contaminated. Yāmuna-tīra-vana-cārī (Jaya Rādhā Mādhava). Yāmuna-tīra, on the bank of the Yamunā . . . just like we go to the seaside, the beach, similarly, there is bank of Yamunā, very nice river, and there are trees. So these boys, Kṛṣṇa and His friends, with their cows they will go and loiter on the bank of the Yamunā and sport and frivolities, everything, so nicely.
So there was no question of education at that time. After the child is grown up, healthy, nice, then he goes to school. Otherwise, first of all eat sumptuously milk, butter and yogurt, and play sufficiently in open air with friends, take care of the cows. This is labor. But it is sporting, very nice. So these things were taught by Kṛṣṇa Himself, although He was the son of king. Then when He was grown-up, His real father took Him charge, Vasudeva. Then He was . . . as kṣatriya . . . He belonged to the kṣatriya family. All other education was given: how to fight, how to rule, everything.
