CC Madhya 25.21

upadeśa lañā kare kṛṣṇa-saṅkīrtana
sarva-loka hāse, gāya, karaye nartana
Word for word: 
upadeśa lañā — getting instructions from Śrī Caitanya Mahāprabhu; kare — join; kṛṣṇa-saṅkīrtana — the saṅkīrtana movement; sarva-loka hāse — everyone began to laugh in pleasure; gāya — chant; karaye nartana — and dance.
Translation: 
As soon as people received instructions from Śrī Caitanya Mahāprabhu, they began to chant the Hare Kṛṣṇa mahā-mantra. Thus everyone laughed, chanted and danced with the Lord.
