When one full year had passed, Brahmā returned and saw that Kṛṣṇa was still engaged as usual with His friends and the calves and cows. Then Kṛṣṇa exhibited all the calves and cowherd boys as four-armed forms of Nārāyaṇa. Brahmā could then understand Kṛṣṇa’s potency, and he was astonished by the pastimes of Kṛṣṇa, his worshipable Lord. Kṛṣṇa, however, bestowed His causeless mercy upon Brahmā and released him from illusion. Thus Brahmā began to offer prayers to glorify the Supreme Personality of Godhead.
