Krsna’s flute His authorized messenger
Sri Caitanya-caritamrta
CC Antya-lila
May the sweet sound of Lord Kṛṣṇa’s flute, His authorized messenger, be glorified.
CC Antya 1.189, Translation and Purport: “‘May the sweet sound of Lord Kṛṣṇa’s flute, His authorized messenger, be glorified, for it expertly releases Śrīmatī Rādhārāṇī from Her shyness and attracts Her from Her home to the forest.’
This verse from the Lalita-mādhava (1.24) is spoken by Gārgī, the daughter of Garga Muni.
