Translation:
At that time, hundreds and thousands of cowherd boys came out of their respective homes in Vrajabhūmi and joined Kṛṣṇa, keeping before them their hundreds and thousands of groups of calves. The boys were very beautiful, and they were equipped with lunch bags, bugles, flutes, and sticks for controlling the calves.
