When there is krsna-kirtana, people, all classes of people, become very much pleased, and they join. As soon as your kirtana will be pure sankirtana, not artificial, not professional… There are many professional dancer. That will not attract. But even if you do not know the art of dancing, if you simply dance in ecstasy for Krsna's love, that will be appreciated by everyone. That will be appreciated by everyone.

Krsnot-kirtana-gana-nartana-parau. These are the art.
