The demons could see the calf and cow, but because of the illusion created by the energy of the Supreme Personality of Godhead, the demons could not forbid them. The great mystic Maya Dānava became aware that the calf and cow were drinking the nectar, and he could understand this to be the unseen power of providence. Thus he spoke to the demons, who were grievously lamenting.
