tāvat sarve vatsa-pālāḥ
paśyato 'jasya tat-kṣaṇāt
vyadṛśyanta ghana-śyāmāḥ
pīta-kauśeya-vāsasaḥ
tāvat - so long; sarve - all; vatsa-pālāḥ - both the calves and the boys tending them; paśyataḥ - while he was watching; ajasya - of Lord Brahmā; tat-kṣaṇāt - immediately; vyadṛśyanta - were seen; ghana-śyāmāḥ - as having a complexion resembling bluish rainclouds; pīta-kauśeya-vāsasaḥ - and dressed in yellow silk garments.
While Brahmā was contemplating, all the calves and cowherd boys immediately transformed into viṣṇu-mūrtis, having bluish complexions and wearing yellow garments. Brahmā was contemplating his own power and the immense, unlimited power of Kṛṣṇa, but before he could come to a conclusion, he saw this immediate transformation.
