In the Tenth Canto, Thirty-fifth Chapter, verse 15, of Śrīmad-Bhāgavatam, the gopīs tell mother Yaśodā, "When your son plays on His flute, Lord Śiva, Lord Brahmā and Indra—although they are supposed to be the greatest learned scholars and personalities—all become bewildered. Although they are all very great personalities, by hearing the sound of Kṛṣṇa's flute they humbly bow down and become grave from studying the sound vibrated."
In his book Vidagdha-mādhava, Śrī Rūpa Gosvāmī thus describes the vibration of Kṛṣṇa's flute: "The sound vibration created by the flute of Kṛṣṇa wonderfully stopped Lord Śiva from playing his ḍiṇḍima drum, and the same flute has caused great sages like the four Kumāras to become disturbed in their meditation. It has caused Lord Brahmā, who was sitting on the lotus flower for the creative function, to become astonished. And Anantadeva, who was calmly holding all the planets on His hood, was moving in this way and that due to the transcendental vibration from Kṛṣṇa's flute, which penetrated through the covering of this universe and reached to the spiritual sky."
