Srimad Bhagavatam 7.15.71

Instructions For Civilized Human Beings

Once there was a sankirtana festival to glorify the Supreme Lord in an assembly of the demigods, and the Gandharvas and Apsaras were invited by the prajapatis to take part in it. PURPORT

Sankirtana means chanting of the holy name of the Lord. The Hare Krsna movement is not a new movement as people sometimes mistakenly think. The Hare Krsna movement is present in every millennium of Lord Brahma's life, and the holy name is chanted in all the higher planetary systems, including Brahmaloka and Candraloka, not to speak of Gandharvaloka and Apsaroloka. The sankirtana movement that was started in this world five hundred years ago by Sri Caitanya Mahaprabhu is therefore not a new movement. Sometimes, because of our bad luck, this movement is stopped, but Sri Caitanya Mahaprabhu and His servants again start the movement for the benefit of the entire word or, indeed, the entire universe.
