“ ‘My dear mother, in this forest, all the birds, after rising on the beautiful branches of the trees, are closing their eyes and, not being attracted by any other sound, are simply listening to the vibration of Kṛṣṇa’s flute. Such birds must be on the same level as great saints.’
Purport
This is a quotation from Śrīmad-Bhāgavatam (10.21.14). This statement was made by the gopīs, who were lamenting in separation from Kṛṣṇa and studying how the inhabitants of Vṛndāvana were enjoying life like saintly persons.
— A.C. Bhaktivedanta Swami Prabhupāda
