Srimad Bhagavatam 1.8.37,
The wild tigers, elephants, bear and deer all together accompanied the Lord, and the Lord accompanied them in sankirtana. By this He proved that by the propagation of the sankirtana movement (congregational chanting and glorifying of the name of the Lord) even the wild animals can live in peace and friendship, and what to speak of men who are supposed to be civilized.
Srimad Bhagavatam Introduction.
