When Govinda plays His flute, the peacocks immediately become mad, as if they had heard the rumbling of a new cloud. When all the animals and trees and plants, either on the top of Govardhana Hill or in the valley, see the dancing of the peacocks, they all stand still and listen to the transcendental sound of the flute with great attention.
