There is a story in The Charitamrita that tells how Lord Caitanya was walking through the forest singing the Lords names. As he goes deeper into the forest and deeper into his kirtan he starts to dance and all of the forest creatures start to dance and chant with him.
Recently this happened in Melbourne Australia when Vaiyasaki, travelling through the forest with his harmonium sat down and started to play and sing the Mahamantra. Hailey Mead caught the event on Video with her hidden camera. Click on the video below and take a look at what happened next:
