Kṛṣṇa was very expert in playing the flute, and the gopīs were captivated by the sound vibration, which was not only attractive to them, but to all living creatures who heard it. One of the gopīs told her friends, "The highest perfection of the eyes is to see Kṛṣṇa and Balarāma entering the forest and playing Their flutes and tending the cows with Their friends."
