Otherwise, why would the supreme controller — whose every desire is already fulfilled and who is the master of liberation and all other transcendental benedictions — enact this pretense with us, who are always to be controlled by Him?
Purport: 

Although Lord Kṛṣṇa is the Absolute Truth, He humbly sent His cowherd boyfriends to beg food from the brāhmaṇas. In so doing, He exposed the brāhmaṇas’ foolish arrogance and established the glories of His own transcendental beauty by attracting their very wives to surrender at His lotus feet.
