The Bhagwata Purana says that when the strains of his flute wafted through Vrindavan, all things became intoxicated with passion. Not even the wives of gods could resist its call. It was as if all of creation for a moment stopped to listen rapt in attention. As he played, clouds bent low to come closer to him, plants and creepers swayed in silent salute, the reeds from which his flute was made wept tears of joy and rivers slowed their pace in involuntary obeisance.
Vallabhacharaya (1479-1531), has categorized the sound of Krishna's flute into five kinds: When the lord plays with his flute to the left, passion awakes in women; when his face is to the right, desire surges in both men and women; when his face points upwards, Kama (physical desire) infuses the gods; and when downwards, animals and birds become its prey; and when he plays straight ahead, even insentient things cannot insulate themselves from its effect.
