antar-vraje tad abalah pragrhita-pucchaih
vatsair itas tata ubhav anukrsyamanau
preksantya ujjhita-grha jahrsur hasantyah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Within the house of Nanda Maharaja, the cowherd ladies would enjoy seeing the pastimes of the babies Rama and Krsna. The babies would catch the ends of the calves’ tails, and the calves would drag Them here and there. When the ladies saw these pastimes, they certainly stopped their household activities and laughed and enjoyed the incidents.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
While crawling in curiosity, Krsna and Balarama would sometimes catch the ends of the tails of calves. The calves, feeling that someone had caught them, would begin to flee here and there, and the babies would hold on very tightly, being afraid of how the calves were moving. The calves, seeing that the babies were holding them tightly, would also become afraid. Then the ladies would come to rescue the babies and gladly laugh. This was their enjoyment.
