(Lord Caitanya and His Associates chanting and dancing)
"Kṛṣṇot-kīrtana-gāna-nartana: always chanting the glories of Kṛṣṇa. Kīrtana, gāna, nartana. Nartana means dancing. Dancing is very good. The more you dance, the more you become light; means the burden of material contamination becomes reduced. Dancing is so nice.
Even if you don't feel ecstasy, if you dance by force, that will also help us. Kṛṣṇot-kīrtana-gāna-nartanau-parau premāmṛtāmbho-nidhī. By dancing, dancing, we shall develop our dormant Kṛṣṇa consciousness, love for Kṛṣṇa. This is a nice process. Kṛṣṇot-kīrtana-gāna-nartana-parau premāmṛtāmbho-nidhī. Then you will merge into the ocean of love for Kṛṣṇa. So this is the highest stage of ecstasy for Kṛṣṇa consciousness, always chanting Kṛṣṇa's name, dancing in ecstasy, and to be merged in the ocean of love for Kṛṣṇa. These are the perfection.
Dhīrādhīra jana-priyau: in this way we shall become friendly to every people, dhīrādhīra. There are two classes of men: dhīra, sober, and other class, rogue. So both of them will be pleased by kṛṣṇot-kīrtana. You have practical experience. When there is kṛṣṇa-kīrtana, people, all classes of people, become very much pleased, and they join. As soon as your kīrtana will be pure saṅkīrtana, 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 Kṛṣṇa's love, that will be appreciated by everyone. That will be appreciated by everyone. Kṛṣṇot-kīrtana-gāna-nartana-parau. These are the art.
One does not require to become a Vedāntist. Simply if one chants Kṛṣṇa's name, holy name, and in ecstasy dances, he's more than a Vedāntist. Actually, vedānti means one who knows the ultimate knowledge, veda. Veda means knowledge. And anta means ultimate. Vedānta. Then what is that ultimate knowledge? Kṛṣṇa. Vedaiś ca sarvair aham eva vedyam (BG 15.15). That is ultimate knowledge. So one who has understood Kṛṣṇa and Kṛṣṇa's love, he's dancing, then what more Vedānta can do? That is the first-class realization of Vedānta. Kṛṣṇot-kīrtana-gāna-nartana-parau."
