Translation: 
Śrī Pañca-tattva themselves danced again and again and thus made it easier to drink nectarean love of Godhead. They danced, cried, laughed and chanted like madmen, and in this way they distributed love of Godhead.
Purport: 

People generally cannot understand the actual meaning of chanting and dancing. Describing the Gosvāmīs, Śrī Śrīnivāsa Ācārya stated, kṛṣṇotkīrtana-gāna-nartana-parau: not only did Lord Caitanya Mahāprabhu and His associates demonstrate this chanting and dancing, but the six Gosvāmīs also followed in the next generation. The present Kṛṣṇa consciousness movement follows the same principle, and therefore simply by chanting and dancing we have received good responses all over the world. It is to be understood, however, that this chanting and dancing do not belong to this material world. They are actually transcendental activities, for the more one engages in chanting and dancing, the more he can taste the nectar of transcendental love of Godhead.
