Inconceivable Lord Krishna
The cows had younger calves who had started sucking milk from their mothers, and some of the cows had newly given birth, but now, because of love, the cows enthusiastically showed their affection for the older calves, which had left off milking. These calves were grown up, but still the mothers wanted to feed them. Therefore Balarāma was a little surprised, and He wanted to inquire from Kṛṣṇa about the reason for their behavior.
